Steroidal compounds of the invention bear a 17.beta.-oxygenated group and a 17.alpha.-.PSI.-alkyl substituted allene group, e.g., 17.alpha.-(penta-1'-2'-dienyl)-estra-4,9-dien-17.beta.-ol-3-one, and are prepared by a procedure, e.g., involving reacting a corresponding intermediate bearing a 17.alpha.-(3'-dialkylamino-3'-alkyl-substituted-1'-propynyl)-group with a complex hydride. The steroidal compounds are useful as pharmaceuticals, e.g., as progestational agents.
