Diastereoselective Pictet-Spengler reaction of 2-arylethylamine bearing an N-(R)-1-(1-naphthyl)ethylcarbamoyl group with arylacetaldehyde gave 1-benzyltetrahydroisoquinoline in good yield with moderate diastereoselectivity. The reaction was applied to asymmetric synthesis of O-methyl derivative of neferine, an alkaloid of the lotus embryo, Nelumbo nucifera Gaertner.
