Methods are described for effecting the molecular rearrangement of 3β-acetoxy-4aα-hydroxy-5β-methyl-A-homo-B-nor steroids into corresponding normal structures of the 6-methylene-5β-H series. NMR spectral data lead to the assignment of the α-configuration to the 4a-hydroxyl group present in the initial steroidal A-homo-B-nor types.
