Article abstract of DOI:10.1016/S0040-4039(00)74873-8

Steroidal olefins 1 and 3 undergo dimethylaluminum chloride-mediated Prins reactions with paraformaldehyde to furnish homoallylic alcohols 4 and 16 as major products. These ene reaction-type intermediates are converted into 6 and 17 by hydroxyl group-assi
