A novel method in steroid chemistry for synthesis of pregna-4,16-dien-3-one-20-yne and pregna-5,16-dien-3β-ol-20-yne, based on the dehydration of Co-complexes of the corresponding 17α-ethynyl-17β-carbinols was investigated.The theoretical possibility of using phenyliodoso trifluoroacetate for the preparative transformation Δ16-17-ethynyl steroids into 21-hydroxy-Δ16-20-ketopregnanes was discovered.
