Abstract:
A compound of formula V in which each R is independently H, substituted or unsubstituted alkyl, aryl, cycloalkyl, heteroalkyl, heteroaryl, or heterocycloalkyl; R1 is hydrogen; an alkyl, alkenyl, alkynyl, heteroalkyl, aryl, heteroaryl, cycloheteroaryl, cycloalkyl, heterocycloalkyl, alkanal, or thioalkanal group, each of which may be unsubstituted or substituted with a substituent selected from amino azido, halogen, hydroxyl, guanidino, carboxy, carboxylic acid ester, thio, carboxamide, alkylamino, dialkylamino, trialkylammonium, and alkoxy; with the provisos that (a) when R1 is hydrogen, then R2 is a protected, unprotected or substituted sugar amino-; a glycosylamino-, or a glycosylamino group of an oligosaccharide; a mono- or oligosaccharide coupled through a substituted or unsubstituted alkylamino-, arylamino-, cycloalkylamino, heteroalkylamino, heteroarylamino or heterocycloalkylamino group; an amino sugar; an amino acid or a peptide linked via a nitrogen atom; and (b) when R1 is an alkyl, alkenyl, alkynyl, heteroalkyl, aryl, heteroaryl, cycloheteroaryl, cycloalkyl, heterocycloalkyl, alkanal, or thioalkanal group, each of which may be substituted or unsubstituted, then R2 is a protected, unprotected or substituted sugar amino-; a glycosylamino-, or a glycosylamino group of an oligosaccharide; a mono- or oligosaccharide coupled through a substituted or unsubstituted alkylamino-, arylamino-, cycloalkylamino, heteroalkylamino, heteroarylamino or heterocycloalkylamino group; an amino sugar; an amino acid or a peptide linked via a nitrogen atom; an alkylamino, dialkylamino, arylamino, or diarylamino group, each of which may be substituted or unsubstituted.
