A 6-substituted-5,6-dihydro-2-pyrone from Cryptocarya strictifolia
摘要:
The structure and absolute configuration of an alpha-pyrone isolated from Cryptocarya strictifolia was elucidated as 6R-(4'R,6'R-dihydroxy-8'-phenyloct-1'-enyl)-5,6-dihydro-2H-pyran-2-one. Pinocembrin and lysicamine were also isolated. (C) 2000 Elsevier Science 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).
