The palladium-catalyzed reaction of 1,2-propadiene, the enol triflate of an alpha-tetralone and the enolate of 2-methyl-1,3-cyclopentanedione leads to compounds such as 1a which are transformed under acidic conditions to steroidal trienones. This approach to the steroid skeleton is presently limited to compounds having an aromatic A-ring.
