Abstract
1,064,011. Steroids. TAKEDA CHEMICAL INDUSTRIES Ltd. Oct. 10, 1963 [Oct. 11, 1962 (2); Nov. 2, 1962; Nov. 24, 1962; Dec. 8, 1962; March 22, 1963], No. 40034/63. Headings C2C and C2U. The invention comprises compounds of the general formulµ wherein R<SP>1</SP> is a hydrogen atom, an alkoxy radical having up to 4 carbon atoms or a phenoxy radical and R<SP>2</SP> is an alkyl radical having up to four carbon atoms or a phenyl or benzyl radical and a process which comprises reducing a 13-substituted-1,3,5(10),8,14-pentaene-17-one with an alkali metal borohydride, alkali metal aluminium hydride, diethyl aluminium hydride or aluminium isopropoxide to form the corresponding 17#-ol, and if desired hydrogenating the latter to form a 13-substituted-gona-1,3,5(10),8-tetraen-17#-ol. The 13 - substituted -1,3,5(10),8,14 -pentaene - 17 - one may be obtained by reacting a compound of the general formula (in which R<SP>1</SP> is a hydrogen atom or an alkoxy radical having up to 4 carbon atoms) with a compound of the formula (in which R<SP>2</SP> is an alkyl radical having up to 4 carbon atoms or a phenyl or benzyl radical) in the presence of a basic catalyst to produce a compound of the general Formula III and dehydrating this compound in the presence of an acid catalyst. The tetraene products may be reduced with an alkali metal in liquid ammonia to obtain the corresponding 1,3,5(10)- trienes. The racemic products obtained may be resolved by acylation of a 17#-hydroxy group with an optically active acid.
