A mild and efficient Mitsunobu protocol for the regioselective alkylation of catechols such as 3,4-dihydroxybenzaldehyde and methyl 3,4-dihydroxybenzoate is described. The para-alkylation products could be easily prepared via the Mitsunobu reaction with high selectivity in moderate to good yields.
描述了一种温和且高效的Mitsunobu协议,用于对儿茶
酚类化合物(如
3,4-二羟基苯甲醛和甲基3,4-二羟基
苯甲酸酯)进行区域选择性烷基化。通过Mitsunobu反应,能够以较高选择性和中等到良好的产率轻松制备对位烷基化产物。
