Catalyst-free dehydrative SN1-type reaction of indolyl alcohols with diverse nucleophiles “on water”†
Abstract
A green and efficient dehydrative SN1-type reaction of indolyl alcohols with diverse nucleophiles was developed using water as the solvent, affording versatile 3-indolyl derivatives in high yields. The advantages of being catalyst-free, environmentally benign, and having a wide substrate scope and easy workup make it a promising method for preparation of indolyl compounds.
