The reaction of (2-aminobenzyl) triphenylphosphonium bromide with aromatic aldehydes or alpha,beta-unsaturated aldehydes under microwave-assisted conditions constitutes a newsynthesis of 2-substituted indoles in high yields (81-97%) in a one-potreaction. The adduct from indole-4-carboxaldehyde was an advanced intermediate in the synthesis of arcyriacyanin A.
