Abstract
A process for the preparation of the 3,17-dihydroxy [δ 2 'or dihydro] [4', 5'-16,17] -isoxazolino 13-Z-gona 1,3,5 (10) -trienes of the general formula: ** (See formula) ** wherein R1 represents hydrogen or a lower alkyl radical; R 2 represents hydrogen or a halogen atom; R3 represents hydrogen, a lower alkyl radical or an organic carboxylic acid residue; Z represents a lower alkyl radical preferably having 1 to 4 carbon atoms; A and B each represent a hydrogen atom or together form a carbon-nitrogen double bond with the restriction that when R2 and R3 represent hydrogen and R1 and Z represent a methyl group, A and B always represent hydrogen, characterized in that it reacts an alkyl alcohol format with a 17-oxo gonatriene of the following general formula: ** (See formula) ** wherein R1 represents hydrogen or a lower alkyl radical, R2 represents hydrogen or a halogen atom and Z a lower alkyl radical having preferably 1 to 4 carbon atoms, then the resulting 16-hydroxymethylene derivative is treated with hydroxylamine to obtain a δ 2 '(4', 5'-16,17) -isoxazolino 17-hydroxy 13-Z-gona I, 3,5 (10) -triene, which by the action of a lower alkyl halide or a functional derivative of a carboxylic acid provides the desired ether or ester at or, by reduction, provides the corresponding dihydrogenated compound.
