Cpds. of formulae I-III X = H, lower alkyl or lower alkanoylthio at 6, or H, lower alkyl, lower alkylthio, lower alkanoylthio or halogen at 7. Z = where R'=OH or lower alkanoyloxy R2 = H or lower alkyl or R' and R2 together = a 17beta-OH, 17alpha-lower alkane-carboxylic acid lactone or =O. R3 = H, lower alkyl, OH or lower alkanoyloxy. R4 = H, lower alkyl, OH, or halogen R5 = H, lower alkyl, OH, or halogen R6 = H, lower alkyl, F, OH or lower alkanoyloxy Intermediates for 9beta,10alpha-steroids. |
