A novel protocol for construction of indolylmethyl group at aldehydes or ketones

Tokuyama,Watanabe,Hayashi,Kurokawa,Peng,Fukuyama

, p. 1403 - 1406 (2007/10/03)

A new method for introduction of indolylmethyl group to aldehydes or ketones using diethyl (o-isocyanophenylmethyl) phosphonate through Horner-Wadsworth-Emmons condensation, thiolmediated radical cyclization, and the subsequent desulfurization is described. The Horner-Wadsworth-Emmons reagent was prepared from 2-nitrobenzaldehyde in a concise three-step sequence.
