Das, Biswanath,Nagendra, Siddavatam,Reddy, Cheruku Ravindra

, p. 1249 - 1254 (2011)

The stereoselective total synthesis of two naturally occurring α-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.
