摘要

Enaminones undergo inverse electron demand Diels–Alder reaction with 1, 3, 5-triazine, allowing access to functionalised quinazolinones as intermediates in the synthesis of CNS agents. This reaction is highly dependent of the solvent: 1, 3, 5-triazine undergoes single or double [4+ 2] cycloadditions with enaminones, and quinazolinones or acridinediones can be selectively obtained.
