Heterogeneous oxidative synthesis of quinazolines over OMS-2 under ligand-free conditions

Author affiliations

Abstract

A manganese oxide octahedral molecular sieve (OMS-2) prepared using urea as an additive was found to be an efficient recyclable catalyst for the synthesis of quinazolines via oxidation/cyclization. A broad range of substituted quinazolines were obtained from alcohols and amidines in good yields under ligand-free conditions. OMS-2 was characterized by XRD, BET, ICP-AES, SEM, TEM and XPS, which indicated that the superior catalytic ability might arise from enhanced surface area and crystallinity.
