The ten-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 5substituted pyrroles 6. With strong nucleophilic substituents at the 5-position,
