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).

A process for preparing N,N,N-trisubstituted nitrogen-containing compounds which comprises contacting a carboxylated N,N,N-trisubstituted nitrogen-containing compound with a mixed metal oxide catalyst under conditions effective to produce the N,N,N-trisubstituted nitrogen-containing compound.
