A simple and efficient route towards unsymmetrical methylenebisphenol derivatives is reported. This straightforward strategy avoids the use of harmful or dangerous chemicals, allowing the synthesis of highly functionalized bisphenyls with no need of protecting groups. The alkylation of the phenyl ring is selective for the para position of the hydroxyl substituent. All methylenebisphenols were obtained
报道了一种制备不对称亚甲基双酚衍生物的简单有效途径。这种简单的策略避免了使用有害或危险的化学品,允许合成高度官能化的双苯基而无需保护基团。苯环的烷基化对羟基取代基的对位是有选择性的。所有亚甲基双酚均以完全区域选择性的方式获得并以高产率分离。
