雌甾C17位引入α-正丁基的研究——17α-正丁基雌二醇-3-环戊醚的合成
A STUDY OF THE INTRODUCTION OF N-BUTYL GROUP ONTO C17-POSITION OF ESTRADIOL——SYNTHESIS OF 17α-n-BUTYL-17β-ESTRADIOL-3-CYCLOPENTYL ETHER
-
Abstract: N-Butyl lithium has been proved to be a convenient reagent for introducing nbutyl group onto C17-position of estrone-3-cyclopentyl ether. Using conventional Grignard's organomagnesium reagent we obtained 3-O-cyclopentyl-3,17β-estradiol instead of the normal adduct.
