Site selective monoacylation of pyrroles has been achieved via Pd(II)-catalyzed C-H activiation with aldehydes in the presence of TBHP as oxidant using the 3-methyl-2-pyridine as directing group. The reaction has been extended to different aromatic and heteroaromatic aldehydes for the synthesis of a series of di(hetero)aryl ketones. The utility of the methodloogy has been demonstrated in the synthesis of pyrrolomycins, as Celastramycin analogues and Tolmetin.
