Asymmetric synthesis of (+)-passifloricin A and its 6-epimer
Chandrasekhar,Rambabu,Reddy, A. Syamprasad
, p. 4476 - 4478 (2008)
Stereoselective total syntheses of the antiprotozoal natural product (+)-passifloricin A and its C-6 epimer have been achieved in ~5% overall yield. The strategy is based on Jacobsen epoxidation, Grubbs' metathesis and an Evans' intramolecular oxa-Michael reaction.
