The oxidation of pyrroles usually leads to uncontrolled polymerization and decomposition. To overcome this problem, the controlled oxidation of substituted pyrroles with Dess-Martin periodinane is reported. This strategy yields a range of 5-aroyloxypyrrolinones.

tetrahydroindolizines and tetrahydropyrrolo[1,2-a]azepines via Brønsted acid-mediated annulation of pyrroles featuring N-tethered α,β-unsaturated esters. In addition, the Brønsted acid-catalyzed cyclization of pyrroles featuring pendant α,β-unsaturatedketones was applied to complete total syntheses of the indolizidine alkaloids (±)-tashiromine and (±)-indolizidine 209I.
