Abstract

1,187,115. 8,14-Seco-steroids. AMERICAN HOME PRODUCTS CORP. 7 April, 1967 [7 April, 1966], No. 53133/69. Divided out of 1,187,113. Heading C2C. Novel seco-steroids of the Formula (II) are prepared by dehydrogenation of seco-steroids of the Formula (III) (wherein R is H, C 1-6 alkyl or C 1-6 alkanoyl; and R<SP>1</SP> is C 1-6 alkyl; and there may optionally be an alkyl or alkoxy group or a halogen atom at one or more of positions 1, 2 and 4). Preferably dehydrogenation is effected in the presence of an oxidizing catalyst in an inert solvent at 70‹ to 160‹ C.
