Abstract
Abstract The tert -butyl ester of 3-methoxy-2-pyrrolecarboxylic acid 3 undergoes reaction with singlet oxygen to form an intermediate imino hydroperoxide 4 . This hydroperoxide may be trapped by a variety of nucleophiles yielding 5-substituted pyrroles 6 . With strong nucleophilic substituents at the 5-position, these pyrroles may add to unreacted hydroperoxide 4 to form bipyrrole-like products 7 .
