Abstract
The invention comprises cyclopentanonaphthalene derivatives of formula <FORM:0928317/IV(a)/1> where -OAc is acyloxy; either X and Y together constitute a double bond and Z is -NR1R2 (R1, R2 are C1-6 alkyl or -NR1R2 is an N or N + O heterocyclic residue), or X is g -chloro-2-butenyl while Y and Z constitute together the oxygen atom of a keto group. The heterocyclic residue may be for example piperidinyl, morpholinyl or pyrrolidinyl. Ac is preferably benzoyl, but may be also, e.g., acetyl, trimethylacetyl, phenoxyacetyl, propionyl, b -cyclopentylpropionyl, phenylpropionyl, 4,4-dimethylpentar???yl, 10-undecanoyl, hexahydroterephthaloyl or hexahydrobenzoyl. The enamines of the invention are prepared by reacting a compound of the above formula, but in which the double bond is in the position common to the 6-membered rings, X is H and YZ is O=, with a secondary amine HNR1R2 in an inert organic solvent. The chlorobutenyl??? compounds of the invention are prepared by reacting an enamine of the invention with the compound X1CH2CH = CCl.CH3 (X1 = halogen); the latter, where X1 = I, is made by reacting an alkali metal iodide (e.g. NaI) with 1,3-dichloro-2-butene in a polar medium such as dimethylformamide. The chlorobutenyl compounds of the invention may be hydrolysed to give products which are of the above general formula, but in which the double bond is now in the 8-position instead of the 9, X is acetonylmethyl and YZ is O=. Specifications 914,732 and 914,735 are referred to.
