摘要

The enantiospecific total synthesis of erythronolide A (1) through (9S)-9-deoxo-9- hydroxyerythronolide A (2) from the chiral C1–C6, C7–C9, and C10–C13 synthetic segments is described. The C10–C13 segment,(3R, 4R, 5R)-5-O-benzyl-2-iodo-3, 4-O- isopropylidene-4-methyl-1-heptene-3, 4, 5-triol (11) was synthesized in 16 steps and an 8.3% overall yield from D-ribose. The C7–C9 segment,(S)-(+)-2-(2-bromo-1-methylethyl)-1 ...
