Abstract

A process for the preparation of 3-oxo 13beta-R 17beta-OX 2-oxa 4,9,11-gonatrienes of the general formula: ** (See formula) ** wherein R represents a lower alkyl and especially the methyl, ethyl, propyl or butyl radical and X represents hydrogen or the acyl radical of an organic acid, characterized in that a 5-oxo 10-hydroxymethyl 13beta-R-17beta-hydroxy is condensed des-A 9,11-gonadiene or an ester thereof with an alcohol halogenacetate in the presence of zinc, the condensation product is treated, a mixture of 5-hydroxy-5-alkoxycarbonylmethyl 10-hydroxymethyl 13beta-R 17beta-hydroxy A 9,11-gonadiene and 3-oxo 5-hydroxy 13beta-R 17beta-hydroxy 2-oxa 9,11-gonadiene or its esters, with an acidic agent and a 3-oxo 13beta-R 17beta-hydroxy is obtained 2-oxa 4,9,11-gonatriene or an ester thereof.
