Allylsilane addition on C-13 of 11-methoxycarbonyl-17-acetyl-1,3,5(10),13(17)-gonatetraenes: a straightforward route to introduce an 18α-methyl group

The conjugate addition of allylsilane (Sakurai reaction) to 11-methoxycarbonyl-17-acetyl-1,3,5(10),13(17)-gonatetraenes provided 13a-allyl steroids. Ozonolysis followed by a decarbonylation affords steroids exhibiting the 18a-methyl group. This new steroid is an estrone derivative.
