Reduction of 1-pyrrolyl and 1-indolyl carbamates to hemiaminals

Hemiaminals of pyrroles and indoles have been prepared from the lithium aluminum hydride reduction of 1-pyrrolyl and 1-indolyl carbamates with good yields (67–82%). These carbamates are more reactive than aliphatic amides and carbamates under the LAH reduction, but less reactive than esters.
