Bridged-ring steroids. II. The synthesis of bridged steroids with a bicycloheptane ring A system

Bridged steroids with a bicycloheptane ring A system are formed on thermolysis of 5-vinyl 3-keto steroids. 5-Vinyl-5α-cholestan-3-one (26) on being heated at 350 deg C in decalin gave 2α,5-(syn-methylmethano)-5α-cholestan-3-one (27).Similar treatme
