Novel compounds are described. The compounds generally comprise an acidic group, a basic group, a substituted amino or N-acyl and a group having an optionally hydroxylated alkane moiety. Pharmaceutical compositions comprising the inhibitors of the invention are also described. Methods of inhibiting neuraminidase in samples suspected of containing neuraminidase are also described. Antigenic materials, polymers, antibodies, conjugates of the compounds of the invention with labels, and assay methods for detecting neuraminidase activity are also described.

The baker'syeastreduction of seven different prochiral nitroketones 1a-g occurred on the re face of the carbonyl group, thus affording the (S)-nitroalcohols 2a-g, with different level of enantioselectivity (e.e. 15–99%). The best results (e.e. = 99%) were achieved when the substituent R is markedly different from the nitroalkyl group [e.g. 1a (R = Me) and 1e (R = o-MeO-C6H4)]. The e.e. and the configuration
Baker的七个不同的前手性硝基酮酵母还原1A-G上发生了重新羰基的面,由此提供第(小号)-nitroalcohols 2A-G ,具有不同水平的对映选择性(EE 15-99%)。当取代基R与硝基烷基显着不同时(例如1a(R = Me)和1e(R = o -MeO-C 6 H 4)),可获得最佳结果(ee = 99%)。通过相应的Mosher酯的NMR研究确定了生物产物的ee和构型,在一种情况下(2d)的化学相关性。还描述了从2d开始的光学活性内酯7和吡咯烷11的合成。
