摘要

The asymmetric dihydroxylation of drim-7-en-11-ol was studied in detail and diastereomerically pure driman-7 alpha,8 alpha,11- and driman-7 beta,8 beta,11-triols were prepared. Further elaboration of driman-7 alpha,8 alpha,11-triol afforded 14,15-bisnorlabd-7 alpha,8 alpha-isopropylidenedioxy-11,13-dione from which a novel chlorinated bisnorlabdanic compound (14,15-bisnorlabd-12-ene-12-chloro-8 alpha,13-epoxy-7 alpha-ol-11-one) and an unusual dichloro-derivative, 13,14,15,16-tetranorlabd-12-dichloro-7 alpha-acetoxy-8 alpha-ol-11-one, were obtained.
