Stereoselective total synthesis of (+)-cryptofolione and (+)-goniothalamin
摘要:
The stereoselective total synthesis of two naturally occurring alpha-pyrone derivatives (+)-cryptofolione and (+)-goniothalamin has been accomplished via a common intermediate. The synthetic sequence involves the asymmetric reduction of a propargyl ketone and olefin cross-metathesis as the key reactions. (C) 2011 Elsevier Ltd. All rights reserved.
