Abstract: L-Tryptophan methyl ester hydrochloride 2 undergoes Pictet-Spengler reaction with aromatic aldehydes in non-acidic aprotic media to furnish tetrahydro--carbolines. The reaction proceeds in good yield and excellent diastereoselectivity giving cis isomers 4a-c and 6a as the major product. Use of an optically active aldehyde 10 for this reaction yields enantiopure cis-1,3-disubstituted 1,2,3,4-tetrahydro--carboline 11.
