An efficient and solvent free method for benzylation, propargylation and allylation of 1,3-dicarbonyl compounds with alcohols has been developed by using La(NO3)3·6H2O as water tolerable catalyst. The reaction was shown to proceed smoothly for various 1,3-dicarbonyl compounds with benzylic, propargylic and allylic alcohols including 10 allylic alcohols, without any solvent, providing a clean access to the desired products in short reaction times with good to excellent yields and high selectivity.
一种高效且无溶剂的方法已被开发,用于1,3-二羧基化合物与醇的苄基化、丙炔基化和烯丙基化,采用La(NO3)3·6H2O作为耐水催化剂。该反应在没有任何溶剂的情况下,对多种1,3-二羧基化合物与苄醇、丙炔醇及烯丙醇(包括10种烯丙醇)进行顺利进行,提供了干净的反应途径,具有短的反应时间、良好至优秀的产率和高选择性。
