Claim:
A compound comprising a compound from formula (1): wherein R 1 is selected from the group consisting of hydrogen, 2- or 3- or 4-halo-phenyl, heteroalkyl, alkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, cycloalkyl, cycloalkylalkyl, heterocyclyl, and heterocyclylalkyl; wherein R 2 is selected from the group consisting of 2- or 3- or 4-halo-phenyl, heteroalkyl, lower alkyl, C 7-25 alkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, cycloalkyl, cycloalkylalkyl, heterocyclyl, and heterocyclylalkyl, wherein, if substituted, the lower alkyl is selected from the group consisting of methyl, n-propyl, isopropyl, n-butyl, t-butyl, and n-pentyl, and wherein aryl in R 2 is unsubstituted or substituted with with one or more substituents selected from the group consisting of —C(O)R, —OR, alkyl, aryl, —N(H)R, -N(R)R, —S—R, —N 3 , —B(R)R, —B(OH) 2 , —B(OR) 2 , —C(O)OH, —C(O)OR, —C(O)NH 2 , —S(O) 2 NH 2 , —C(O)N(H)R, —C(O)N(R)R, —SH, —S—R, —NO 2 , cyano, halo, haloalkyl, haloalkoxy, heterocyclyl, heteroalkyl, —OH, —OC(O)R, —C(O)R and —C(O)CH a X b , wherein a+b=3 and X is selected from the group consisting of F, Cl or Br, and wherein R is alkyl having less than twelve carbons; wherein R 3 is selected from the group consisting of —B(R 4 R 5 ), —R 6 —B(R 4 R 5 ), aryl, arylalkyl, cycloalkyl, heteroaryl, heteroarylalkyl, heterocyclyl, heterocyclylalkyl, —C(O)—R 6 , —O—R 6 , —S(O) y —R 6 (wherein y=0, 1, or 2), —P(O)—(R 4 R 5 ), and —N(R 7 R 8 ); wherein R 6 is selected from the group consisting of alkyl, aryl, arylalkyl, cycloalkyl, heteroaryl, heteroarylalkyl, heterocyclyl, and heterocyclylalkyl; wherein R 4 and R 5 are independently selected from the group consisting of hydrogen, hydroxyl, aryloxy, and alkoxy, or wherein R 4 and R 5 together form a cyclic ester, or an acid anhydride (either mixed or symmetrical); wherein R 7 and R 8 are independently selected from the group consisting of from hydrogen, alkyl, haloalkyl, aryl, cycloalkyl, arylalkyl, heteroalkyl, heterocyclyl and heterocyclylalkyl; R 7 and R 8 are both oxygen; or R 7 and R 8 form a heterocyclyl; and wherein X 2 is —S(O) y- (wherein y=0, 1, or 2) or oxygen; and n is an integer between 1 and 8.
