Summary:1,128,790. Steroids. ROUSSEL-UCLAF. 21 Oct., 1966 [19 April, 1966], No. 13139/68. Divided out of 1,128,786. Heading C2U. Novel 7 - alkyl - gona - 4,9 - dien - 3 - ones of the general formula wherein A is an hydroxy or hydroperoxy group, R5 is an alkyl group, R6 is a substituted or unsubstituted alkynyl group, and R7 is an alkyl group, are obtained by reacting the corresponding gona-5(10),9(11 )-diene-3-one with oxygen to give the desired 11#-hydroperoxy derivative which may be reduced to the corresponding 11#-hydroxy derivative, e.g. with triethyl phosphite.
