Abstract

A potential and convenient protocol for the synthesis of 4-arylquinazolines and 4-aminoquinazolines by electrocyclisation of N-arylamino-1,3-diazabuta-1,3-dienes is described.

Key words

quinazolines - electrocyclisation - N-arylamino-1,3-diazabuta-1,3-dienes - intramolecular H-bonding - amino-substituted quinazolines
