摘要：

Two new highly stereoselective routes to (2R,3S,4R)-3-(tert-butyldimethylsilanyloxy)-2,4-dimethyl-5-oxopentanoic acid methoxymethylamide, an important intermediate in natural product synthesis, are described. Both schemes are considerably shorter and less expensive than methods previously reported. The title compound was then converted to direct precursors of C1-C7 and C17-24 fragments of the potent microtubule stabilizer (+)-discodermolide. (C) 2002 Elsevier Science Ltd. All rights reserved.
