Asymmetric synthesis of cryptofolione and determination of its absolute configuration

Two possible stereoisomers of cryptofolione, isolated from the Cryptocarya species in South Africa and Brazil, were synthesized in an enantioselective manner by using asymmetric hetero Diels-Alder reaction as the key steps. Comparative evaluation of the
