A flexible synthesis of 2,3-disubstituted indoles from aminobenzyl phosphonium salts. A direct synthesis of rutaecarpine

Kraus, George A.,Guo, Haitao

, p. 5337 - 5341 (2009)

(Chemical Equation Presented) The reaction of substituted (2-aminobenzyl)triphenylphosphonium bromides with aromatic aldehydes or α,β-unsaturated aldehydes constitutes a new synthesis of 2,3-disubstitued indoles in high yields. The adduct from 4-oxo-3,4- dihydroquinazoline-2-carbaldehyde was an advanced intermediate in the synthesis of several rutaecarpines.
