Stereoselective total synthesis of (+)-anamarine via cross-metathesis protocol
摘要:
A convergent stereoselective total synthesis of (+)-anamarine via cross-metathesis (CM) protocol starting from 2-butyn-1,4-diol and vinyl lactone is reported. Other key features of the strategy include the use of Sharpless asymmetric epoxidation, Sharpless dihydroxylation, and Red-Al reduction. (C) 2010 Elsevier Ltd. All rights reserved.

Ring‐closing metathesis (RCM) and olefin cross‐metathesis (CM) reactions were used as the key steps for the synthesis of (+)‐cryptocaryalactone (1) and the first synthesis of the diastereoisomer 3 of (+)‐strictifolione, starting from the commercially available L‐malic acid (=(2S)‐2‐hydroxybutanedioic acid).
