Abstract: Abstract Pyrrole formiate derivatives were synthesized through ring contraction of corresponding 3-carboxylate-1,4-dihydropyridines (3-CDHPs) mediated by 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO). 2-Carboxylate-3-aryl-1H-pyrroles (2) and 3-carboxylate-4-aryl-1H-pyrroles (3) were obtained under readily accessible reaction conditions. To gain deep insights into this… read more here.
