In a representative chemical synthesis, 6-methoxy-alpha-tetralone is reacted with vinylmagnesium bromide, and the resulting 1,2,3,4-tetrahydro-6-methoxy-1-vinyl-1-naphthol is condensed with 2-ethyl-1,3-cyclopentanedione to form initially a tricyclic intermediate (secosteroid) containing all of the gonane skeleton carbon atoms. Cyclization of the secosteroid via dehydration yields a 13-ethylgona-1,3,5(10)-8,14-pentaene structure which is then successively reduced and ethynylated.Prepn: H.
