In the presence of a catalytic amount of Bi(OTf)3·4H2O and under microwave irradiation, neat mixtures of epoxides and amines afforded smoothly the corresponding 2-amino alcohols. A wide variety of aliphatic amines were reacted with cycloalkene oxide, styrene oxide, and stilbene oxide. The reaction proceeded rapidly and afforded the 2-amino alcohols in high up to quantitative yields. All products could
在催化量的Bi(OTf)3 ·4H 2 O的存在下,在微波辐射下,环氧化物和胺的纯净混合物可平稳地得到相应的2-氨基醇。使多种脂族胺与环氧化烯,氧化苯乙烯和氧化二苯乙烯反应。反应进行得很快,并以高至定量的产率得到了2-氨基醇。通过简单过滤,无需水后处理即可获得所有产品。
