The use of 1-tert-butoxy-2-tert-butoxycarbonyl-1,2-dihydroisoquinoline (BBDI) as a tert-butoxycarbonylation reagent for acidic proton-containing substrates such as phenols, aromatic and aliphatic amines hydrochlorides, and aromatic carboxylic acids in the absence of a base is described. The reactions proceed chemoselectively in high yield under mild conditions.
1-叔丁氧基-2-叔丁氧基羰基-1,2-二氢异喹啉(BBDI)作为叔丁氧基羰基化试剂用于酸性质子质底物(例如苯酚,芳族和脂肪族胺盐酸盐以及芳香族羧酸)的用途描述了不存在碱的情况。在温和条件下,该反应以高产率进行化学选择。
