Synthesis of heterocyclic steroids—III : An unsuccessful attempt at the synthesis of B-nor-6-thiaequilenin through 3-cyano-7-methoxy-4-oxo-1,2,3,4-Tetrahydrodibenzothiophene (cas 16587-33-0)☆

The synthesis of 3-cyano-7-methoxy-3-methyl-4-oxo-1,2,3,4-tetrahydrodibenzothiophene is described. The latter could not be converted to B-nor-6-thiaequilenin, the thioster of equilenin since it failed to undergo Stobbe Condensation with diethyl succinate.
