  C-3- and C-4-Alkylated Polyhydroxypyrrolidines:  Enantiospecific Syntheses and Glycosidase Inhibitory Activity

  摘要：

  Short, efficient, and stereoselective syntheses of enantiomerically pure C-3- and C-4-alkylated analogues of (2R,3S,4R)-3,4-dihydroxy-2-(hydroxymethyl) a potent alpha-galactosidase inhibitor, from 4-hydroxy-L-proline are presented. Grignard addition or enolate alkylation of a N-(9-phenylfluoren-9-yl)-4-oxo-3-[(methoxymethyl)oxy]proline and epoxidation or hydroboration of a 4-methylene-3-[(methoxymethyl)oxy]proline proceeded with complete stereoselection and in excellent yields. The inhibitory activities of the synthesized pyrrolidines were measured and showed that the fit of A. niger alpha-galactosidase and the jack bean alpha-mannosidase around C-3 of the pyrrolidine ring (alpha face) must be very tight, while the fit around C-4 (alpha face) is much looser. Positioning a methylene group between the hydroxyl at C-4 and the pyrrolidine ring completely abolishes the inhibitory activity (see analogue 5).
