Triphenylethylenes having an N-(dialkylaminoalkyl)alkanesulfonamide substituent in the one of the phenyl rings may be prepared from similarly substituted benzophenones by reaction thereof with a benzyl Grignard reagent followed by dehydration of the resulting triphenylethanol intermediate and if desired chlorination or nitration of the resulting product. The triphenylethylenes have estrogenic and post-coital antifertility action and are useful as intermediates for the preparation of other triphenylethylene compounds.
在其中一个苯环中具有N-(二烷基氨基烷基)烷磺酰胺取代基的三苯乙烯可以通过将类似取代的苯甲酮与苄基格氏试剂反应制备而成,然后脱水得到三苯乙醇中间体,最后如果需要可以对产物进行氯化或硝化。这些三苯乙烯具有雌激素和事后避孕作用,并且可用作其他三苯乙烯化合物的制备中间体。
