Abstract

The invention comprises 1-acyloxy-6-keto-7-(g - keto - butyl)-7,7a-epoxy-9a-methyl-3a,3b,4,5,8,9 - hexahydro-cyclopentano-[2,1-c]-naphthalenes of the general formula <FORM:0914734/IV (b)/1> in which -OAc represents an acyloxy radical derived from an aliphatic, araliphatic or aromatic carboxylic acid and a process for the preparation thereof which comprises reacting a 1-acyloxy-6-keto-7-(g -keto-butyl)-9a-methyl-3a,3b,4,5,8,9 - hexahydro-cyclopentano-[2,1-c]-naphthalene with a per acid as oxidizing agent so as to introduce an epoxy configuration and thus to form the corresponding 1-acyloxy-6-keto-7-(g -keto-butyl)-7,7a-epoxy - 9a - methyl-3a,3b,4,5,8,9 - hexahydro-cyclopentano-[2,1-c]-naphthalene, the acyloxy radical being as defined above. The 1-acyloxy-6-keto-7-(g -keto-butyl) - 9a - methyl - 3a,3b,4,5,8,9-hexahydro-cyclopentano-[2,1-c]-naphthalene employed as starting material may be formed by condensing the corresponding 1-acyloxy-6-keto-9a-methyl - 3a,4,5,7,8,9 - hexahydro-cyclopentano-[2,1-c]-naphthalene with a ,g -dichloro-2-butene to form the corresponding 1-acyloxy-6-keto-7-(g -chloro - 2 - butenyl)-9a-methyl-3a,4,5,7,8,9-hexahydro-cyclopentano - [2,1-c] - naphthalene and hydrolysing the product. The example relates to the preparation of the compound of the above general formula in which -OAc is a benzyloxy group. Specification 914,732 is referred to.
