Abstract

The invention comprises 1-acyloxy-6-keto-7-(g - chloro - 2 - butenyl)-9a-methyl-3a,4,5,7,8,9-hexahydro-cyclopentano-[2,1, c]-naphthalenes of the general formula <FORM:0914739/IV (b)/1> where OAc is an acyloxy radical derived from an aliphatic, araliphatic or aromatic carboxylic acid and a process for their preparation by reacting a 1-acyloxy-6-keto-9a-methyl-3a,4,5,7,8,9-hexahydro-cyclopentano - [2,1,c] - naphthalene with 1,3-dichloro-2-butene, e.g. in toluene in the presence of sodium tert. amylate. The cyclic starting material may be prepared by hydrolysing with an organic acid the corresponding 1-acyloxy-6-alkoxy-9a-methyl-3a,4,7,8,9-pentahydro-cyclopentano - [2,1,c] - naphthalene by the process described in Specification 901,851. The compounds of the invention may be converted by means of hydrolysis to the corresponding 1 - acyloxy - 6 - keto - 7-(g -keto-butyl) - 9a - methyl - 3a,3b,4,5,8,9-hexahydro-cyclopentano-[2,1,c]-naphthalenes which are described in Specification 914,732. Examples describe the preparation of benzoyloxy compounds. Specification 914,733 also is referred to.
