Abstract
δ-Oxo acids VI-IX and XIV were converted to δ-thioenol lactones X-XIII and XV on reaction with phosphorus pentasulfide in pyridine. Under these conditions the ε-oxo acid XVI affords B-norsteroids XVII and XVIII. The proposed structures are confirmed by a number of physico-chemical data. The reduction of these thienol lactones with hydrides is also described.
