A process for the preparation of optionally asymmetric acetal compounds, comprising reacting a compound containing a hydroxyl group with a vinylether compound in the presence of a zwitterionic catalyst including at least one basic nitrogen containing structural fragment and at least one sulfonic acid group in its structure, with the proviso that the basic nitrogen on sulfonic acid molar ratio is 1 over 1.
一种制备可选择性不对称缩醛化合物的方法,包括在带有至少一个碱性氮结构基团和至少一个磺酸基团的偶极催化剂存在下,将含有羟基的化合物与乙烯基醚化合物反应,但碱性氮和磺酸的摩尔比为1比1。
