A concise synthetic route to optically active cis-β,γ-disubstituted-γ-butyrolactones via tandem Michael–MPV reaction: new total synthesis of (−)-cis-whisky lactone and (−)-cis-cognac lactone
摘要:
Optically active cis-beta,gamma-disubstituted-gamma-butyrolactones, for example, cis-whisky lactone and cis-cognac lactone, were readily synthesized by using tandem Michael-Meerwein-Ponndorf-Verley reactions that employed (-)-10-mercapto-isoborneol as a chiral template in the key step.
