摘要
A stereoselective synthesis of 1,4-dideoxy-1,4-imino-D-allitol 1 and formal synthesis of (2S,3R,4S)-3,4-dihydroxyproline was achieved via the addition of vinylmagnesium bromide to the benzylimine derived from (R)-2,3-O-isopropylidene glyceraldehyde followed by N-allylation, ring-closing metathesis (RCM), and dihydroxylation.
