研究了4-β,5-β-和4-α,5-α-环氧雄烷-3,17,19-三酮(2)和(7)在酸和碱催化下的反应,以确定这些化合物中的环氧基是否会导致C-10取代基的消除和雌酮(25)的生成。然而,所得到的产物表明,在所考察的条件下,环氧化物的溶剂分解或重排伴随着环氧化物的开放是主要的反应方式。
The acid- and base-catalysed reactions of 4β, 5β- and 4α, 5α-epoxyandrostane-3,17,19-triones (2) and (7) have been examined to see if epoxide opening in these compounds would result in elimination of the C-10 substituent and the subsequent formation of estrone (25). However, the products obtained indicated that epoxide solvolysis or rearrangement concomitant with epoxide opening is the predominant mode of reaction under the conditions examined.
