摘　　要：将1,3-二溴丙烷与醇、羧酸和胺反应得到烯丙基化合物。本文运用“一锅法”策略,首先以雌二醇为原料在碱作用下与1,3-二溴丙烷反应,并考察此烯丙基化反应的最佳条件,之后在最佳条件下将其他醇、羧酸和胺替代雌二醇进行反应。实验结果显示,雌二醇与1,3-二溴丙烷在NaH作用下反应得到3,17β-二烯丙氧基雌二醇-1,3,5(10)-三烯而非3-溴丙基衍生物。因此,1,3-二溴丙烷与其他醇、羧酸和胺的“一锅法”反应可在温和条件下以较高产率得到烯丙醚、烯丙酯和烯丙胺。1,3-Dibromopropane was reacted with alcohol,carboxylic acid and amine respectively to obtain a series of allyl compounds.The one-pot approach was used in this study.Firstly,estradiol as a raw material reacted with 1,3-dibromopropane under the action of alkali then the best conditions for this allylation reaction were determined.Under the best conditions,estradiol was replaced with other alcohols,carboxylic acids and amines for the reaction.The experimental results showed that the reaction of estradiol and 1,3-dibromopropane under the action of NaH alkali produced 3,17β-diallyloxyestradiol-1,3,5(10)-triene instead of 3-bromopropyl.The reaction of 1,3-dibromopropane with other alcohols,carboxylic acids and amines got higher yield of allyl ethers,allyl esters and allylamines under relatively mild conditions.
