The optically active tetracycle 2 with six correct chiral centres common to numerous quassinoids is constructed from (S)-carvone and 3-methyl-2,5-dihydrothiophene S,S-dioxide involving highly regioselective and stereocontrolled reactions.
通过高度区域选择性和立体控制反应,从 (S)- 香芹酮和 3-甲基-2,5-二氢噻吩 S,S-二氧化物制备出了具有光学活性的四环 2,该四环 2 有六个正确的手性中心,是众多类喹喔啉的共同特征。
