, p. 341 - 342 (1992)
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.
Synthesis of Optically Active Tetracyclic Quassinoid Skeleton
Shing, Tony K. M.,Tang, Ying
, p. 1625 - 1632 (2007/10/02)
Tetracyclic quassinoid skeletons 2 and 22 with six correct chiral centres common to numerous quassinoids are constructed from (S)-carvone and 3-methylsulfolene by a 16-step and 13-step reaction sequence involving highly regioselective and stereocontrolled
