simple method for the cleavage of methoxymethyl (MOM)-ether and ester derivatives using bismuth trichloride (BiCl3) is described. The alkyl, alkenyl, alkynyl, benzyl and anthracene MOM ether derivatives, as well as MOM esters of both aliphatic and aromatic carboxylic acids, were deprotected in good yields. To better understand the molecular roles of BiCl3 and water for MOM cleavage, two possible binding
描述了一种使用三氯化铋(BiCl 3)裂解甲氧基甲基(MOM)-醚和酯衍生物的简单方法。烷基,烯基,炔基,苄基和蒽MOM醚衍生物以及脂肪族和芳香族羧酸的MOM酯均以良好的收率进行了脱保护。为了更好地理解BiCl 3和水在MOM裂解中的分子作用,使用密度泛函理论(DFT)方法研究了两种可能的结合途径。理论结果表明,酚和醇MOM底物对Bi原子的初始结合位点偏好不同,这表明水在促进MOM基团的裂解中起着关键作用。
