Abstract

The invention comprises 1-acyloxy-6-keto-7-(g - keto - butyl)-9a-methyl-3a,3b,4,5,8,9-hexahydro-cyclopentano-[2,1, c]-naphthalenes of the formula <FORM:0914732/IV (b)/1> where -OAc represents an acyloxy radical derived from an aliphatic, araliphatic or aromatic carboxylic acid and a process for their preparation which comprises condensing a 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 latter compound. In the example, in which the benzoyloxy compound is prepared, the condensation is carried out in toluene in the presence of sodium tert. amylate and the hydrolysis by means of sulphuric acid. Specifications 901,851, 914,733 and 914,739 are referred to.
