Abstract
1324613 Estrenes ROUSSEF UCLAF 19 April 1971 [11 Feb 1970] 36201/72 Divided out of 1324612 Heading C2U The invention comprises compounds of Formulae VI, VII, VIII, IX, X, XI and XV (wherein K is a ketal group) and their preparation by the routes shown. The conversion of IV into V or XII is effected by photolysis, e.g. with a mercury vapour lamp. In the presence of iodine V is obtained and in its absence XII is obtained. The conversion of V to VI is effected with a strong base. The conversion XII # XIII # XIV # VI is effected by the successive action of an acid, a reducing agent and an acid. The other conversions shown in the Reaction Scheme are conventional.
