DETAILED DESCRIPTION OF THE INVENTION The invention is described herein in detail using the terms defined below unless otherwise specified. The term "alkyl" refers to a monovalent alkane (hydrocarbon) derived radical containing from 1 to 10 carbon atoms unless otherwise defined. It may be straight, branched or cyclic. Preferred alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, t-butyl, cyclopentyl and cyclohexyl. When substituted, alkyl groups may be substituted with up to four substituent groups, selected from R" and R 1 , as defined, at any available point of attachment. When the alkyl group is said to be substituted with an alkyl group, this is used interchangeably with "branched alkyl group". Cycloalkyl is a specie of alkyl containing from 3 to 15 carbon atoms, without alternating or resonating double bonds between carbon atoms. It may contain from 1 to 4 rings which are fused. The term "alkenyl" refers to a hydrocarbon radical straight, branched or cyclic containing from 2 to 10 carbon atoms and at least one carbon to carbon double bond. Preferred alkenyl groups include ethenyl, propenyl, butenyl and cyclohexenyl. The term "alkynyl" refers to a hydrocarbon radical straight or branched, containing from 2 to 10 carbon atoms and at least one carbon to carbon triple bond. Preferred alkynyl groups include ethynyl, propynyl and butynyl. Aryl refers to aromatic rings e.g., phenyl, substituted phenyl and the like, as well as rings which are fused, e.g., naphthyl, phenanthrenyl and the like. An aryl group thus contains at least one ring having at least 6 atoms, with up to five such rings being present, containing up to 22 atoms therein, with alternating (resonating) double bonds between adjacent carbon atoms or suitable heteroatoms. The preferred aryl groups are phenyl, naphthyl and phenanthrenyl. Aryl groups may likewise be substituted as defined. Preferred substituted aryls include phenyl and naphthyl. Heteroaryl refers to a monocyclic aromatic hydrocarbon group having 5 or 6 ring atoms, or a poly cyclic aromatic group having 8 to 16 atoms, containing at least one heteroatom, O, S, S(O), SO2 or N, in which a carbon or nitrogen atom is the point of attachment, and in which one or two additional carbon atoms is optionally replaced by a heteroatom selected from O or S, and in which from 1 to 3 additional carbon atoms are optionally replaced by nitrogen heteroatoms, said heteroaryl group being optionally substituted as described herein. Examples of this type are pyrrole, pyridine, oxazole, thiazole and oxazine. Additional nitrogen atoms may be present together with the first nitrogen and oxygen or sulfur, giving, e.g., thiadiazole and the like. Examples of polycyclic heteroaromatics include benzopyrans, benzofurans, benzopyrroles, benzimidazoles, benzothiazoles, quinolines, purines, isoquinolines, benzopyrimidines, dibenzofurans, dibenzothiophenes, 1,8-naphthosultams, The term "heterocycle" (heterocyclyl) refers to a 5-16 membered cycloalkyl group (nonaromatic) with 1-4 rings, in which one of the carbon atoms in the ring is replaced by a heteroatom selected from O, S or N, and in which up to three additional carbon atoms may be replaced by heteroatoms. The term "heteroatom" means O, S, S(O), S(O) 2 or N, selected on an independent basis. Heteroarylium refers to heteroaryl groups bearing a quaternary nitrogen atom and thus a positive charge. Examples include the following: CH, When a charge is shown on a particular nitrogen atom in a ring which contains one or more additional nitrogen atoms, it is understood that the charge may reside on a different nitrogen atom in the ring by virtue of charge resonance that occurs. and The term "heterocycloalkyl" refers to a cycloalkyl group (nonaromatic) in which one of the carbon atoms in the ring is replaced by a heteroatom selected from O, S or N, and in which up to three additional carbon atoms may be replaced by hetero atoms. The terms "quaternary nitrogen" and "positive charge" refer to tetravalent, positively charged nitrogen atoms including, e.g., the positively charged nitrogen in a tetraalkylammonium group (e. g. tetramethylammonium), heteroarylium, (e.g., N-methyl- pyridinium), basic nitrogens which are protonated at physiological pH, and the like.

Suitable protecting groups for the compounds of the present invention will be recognized from the present application taking into account the level of skill in the art, and with reference to standard textbooks, such as Greene, T. W. et al. Protective Groups in Organic Synthesis Wiley, New York (1991). Examples of suitable protecting groups are contained throughout the specification. In some of the compounds of the present invention, P, P Λ . and P* represent hydroxyl and carboxyl protecting groups, respectively. Likewise, Y may represent a protecting group for X, which in turn represents O or N (see compound 4 below).

In the alternative, X and Y can be considered in combination to represent a ring system, containing from 1-4 rings comprised of from 5 to 16 atoms, 0 to 3 of which are N atoms, and 0 to 2 of which are selected from O, S, S(O) and S(0) 2 .

PREPARATIVE EXAMPLE 1 SYNTHESIS OF 4-(2-(TRIMETHYLSILYLOXY)-ETHYL)-l,8- NAPHTHOSULTAM 70:30 + minor isomers Step 1: potassium l-(methoxycarbonylmethyl)-4-naphthalene sulfonate A solution of methyl 1-naphthaleneacetate (1 mL, 5.77 mmol) in carbon tetrachloride (1 mL) was cooled under nitrogen in an ice bath. Chlorosulfonic acid (0.38 mL, 5.7 mmol) was added dropwise over 8 minutes. After an additional 30 minutes, the viscous mixture was removed from the bath and was stirred at room temperature for 17 hours to give a white solid. The solid was partitioned between methylene chloride (5 mL) and water (5 mL). After filtering through solka-floc, the methylene chloride layer was extracted with more water (2 x 5 mL), and the combined aqueous extracts were basified with potassium carbonate to give a precipitate. The suspension was concentrated to approximately 5 mL and was cooled in an ice bath. The suspension was then filtered and the collected solid was washed with cold water (2 mL). The solid was dried under a stream of nitrogen to give the title compound as a white solid (0.84 g). !H NMR (DMSO-d6, 500 MHz) δ 3.73 (s, OMe), 4.27 (s, CH2Ar), 7.53 (d, ArH), 7.71 (t, ArH), 7.76 (t, ArH), 8.06 (d, ArH), 8.10 (d, ArH) and 8.73 (d, ArH). Step 2: l-(methoxycarbonylmethyl)-5-nitro-4-naphthalene sulfonic acid Potassium l-(methoxycarbonylmethyl)-4-naphthalene sulfonate (10 g, 31.4 mmol) was added portionwise over 30 minutes to 90% nitric acid, which was cooled in a methanol / ice bath to approximately -15 ° C. After 2 hours, the bath temperature had reached -10°C and diethyl ether (200 mL) was added to the mixture. The precipitated solid was filtered, washed with ether (100 mL) and isopropanol (20 mL), and dried under a stream of nitrogen to give the title compound as an approximately 70:30 mixture of the 5- and 8-nitro isomers (approximately 12 g). lH NMR (D2O, 500 MHz) δ 3.69 (s, OMe), 4.30 (s, CH2Ar), 7.67 (t, ArH), 7.71 (d, ArH), 8.18 (d, ArH), 8.29 (d, ArH) and 8.33 (d, ArH). Step 3: sodium l-(methoxycarbonylmethyl)-5-amino-4-naphthalene sulfonate l-(methoxycarbonylmethyl)-5-nitro-4-naphthalene sulfonic acid (2 g, 6.15 mmol) was dissolved in water (20 mL), containing 0.5 mL concentrated sulfuric acid, and was added dropwise over 5 minutes to a refluxing suspension of iron (4 g, 71.6 mmol) in water (100 mL). After refluxing for one hour, the dark mixture was cooled to room temperature, made basic with sodium carbonate, and concentrated to approximately 30mL. The residual mixture was placed on a CG-161 amberchrom resin column (2.5 x 30 cm). The column was washed with water (200 mL), 10% MeCN/ H2θ(200 mL), and 25% MeCN/ H2O (400 mL), collecting 25 mL fractions.
