poor resolutions were usually obtained for the hydroxylation reactions. Transformation of 1 by Cunninghamella blakesleeana gave 6 beta-, 7 beta-, 10 beta-, 15 alpha-hydroxy derivatives 4, 5, 6, 7, and 6 beta,10 beta-dihydroxy derivative 8; transformation of 1 by Cunninghamellaechinulata afforded 5, 6, and 8. Biotransformation of dl-1 by Cunninghamella species usually gave 10 beta-hydroxy product with
