Unique reactivity: In the presence of more reactive amine and alcohol functional groups and of carboxylic acids, the chemoselective N‐acylation of indoles (see scheme) and oxazolidinones is achieved by taking advantage of the unique reactivity of carbonylazole acylating agents with catalytic amounts of 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU).
独特的反应性:在存在更多的反应性胺和醇官能团以及羧酸的情况下,吲哚和恶唑烷酮的化学选择性N-酰化是通过利用催化量为1的羰基唑酰化剂的独特反应性来实现的,8-二氮杂双环[5.4.0]十一月-7-烯(DBU)。
