and phenols to O-allyl compounds (allyl ethers and acrolein acetals), catalyzed by [RuCl2(PPh3)3], was examined. Intramolecular addition of an OH group, leading to the formation of cyclic acetals and orthoesters, was also investigated. As a result, a new, selective and convenient method for the synthesis of symmetrical and unsymmetrical (mixed) acetals and orthoesters was developed.
考察了在[RuCl 2(PPh 3)3 ]催化下,将醇和酚添加到O-烯丙基化合物(烯丙基醚和丙烯醛缩醛)中。还研究了分子内加成OH基团,导致形成环缩醛和原酸酯。结果,开发了一种新的,选择性的和方便的合成对称和不对称(混合)乙缩醛和原酸酯的方法。
