NEW SYNTHESIS OF TWO OPTICALLY ACTIVE STEROID CD RING SYNTHONS BY MICROBIAL ASYMMETRIC REDUCTION

Two optically active steroid CD ring synthons 4 and 19 were synthesized from 11 obtained by the microbial asymmetric reduction of a pro-chiral trione 10 which could be efficiently prepared by the reaction of a new annelating reagent 9 with 2-ethyl-cyclope
