Improved synthesis of 7‐dehydrositosterol

Improved synthesis of 7‐dehydrositosterol

Sitosteryl acetate was brominated in petroleum ether by the gradual addition of N‐bromosuccinimide to a refluxing, illuminated solution and dehydrobrominated by the dropwise addition of the bromo derivative to a refluxing solution of collidine in mesitylene to give a 38% yield of 7‐dehydrositosteryl...
