✦ Synopsis


Two erythro-isomers of 2,2%-dimethoxy-4-(3-hydroxy-1-propenyl)-4%-(1,2,3-trihydroxypropyl)diphenyl ether, (7%S, 8%S)-9 and (7%R, 8%R)-9, were synthesized in seven steps, in which an improved method for the synthesis of the key intermediate 3 was developed. The absolute configuration of the target molecules was also confirmed.

A stereoselective synthesis of (1 0 S,3R,4R)-4-acetoxy-3-(2 0 -fluoro-1 0 -trimethylsilyloxyethyl)-2-azetidinone as a new fluorine-containing intermediate towards b-lactams, is described. The synthetic key step relies upon the dynamic kinetic resolution (DKR) of ethyl 2-benzamidomethyl-4-fluoro-3-ox
