Facile syntheses of cyclopnellitol and its (1R,6S)-, (1R,2S,6S)-, (2S)-diastereoisomers from (–)-quinic acid
Abstract
Cyclophellitol and its (1R,6S)-, (1R,2S,6S)-, (2S)-diastereoisomers are constructed from quinic acid involving a regioselective cyclic sulfate ring opening reaction, a regiospecific oxidative elimination, and an epoxidation reaction.
