Abstract

Arylamines undergo smooth cyclization with 2-deoxy-d-ribose on the surface of montmorillonite KSF clay under mild conditions to afford the corresponding sugar-derived chiral tetrahydroquinolines in high yields with moderate diastereoselectivity. The assignment of the stereochemistry of the product was achieved by various NMR studies.
