Methoxybenzyl protecting groups of alcohols were readily and efficiently removed with DDQ in CH2Cl2-H2O at room temperature. Under these neutral conditions, other usual protecting groups, isopropylidene, methoxymethyl, benzyloxymethyl, tetrahydropyranyl, acetyl, t-butyldimethylsilyl, benzyl, benzoyl, and tosyl, as well as functional groups, epoxide, double bond, and ketone, were remained unchanged
室温下,在CH 2 Cl 2 -H 2 O中用DDQ可以轻松有效地除去醇的甲氧基苄基保护基。在这些中性条件下,其他常用的保护基,异丙基,甲氧基甲基,苄氧基甲基,四氢吡喃基,乙酰基,叔丁基二甲基甲硅烷基,苄基,苯甲酰基和甲苯磺酰基以及官能团,环氧化物,双键和酮保持不变。
