Introduction of the 16α-Hydroxyl Group into Œstrogens by Streptomycetes

Abstract

PAPERS concerned with the microbiological transformation of steroids have appeared frequently in the past seven years; however, no examples of the hydroxylation of steroids with a benzenoid A ring have been observed. We have been able to introduce a hydroxyl group into the 16α-position of œstrone and œstradiol with two strains of Streptomyces halstedii (ATCC 13,499 and NRRL B-2138) and Streptomyces mediocidicus ATCC 13,278.
