Low melting mixture of maltose–dimethylurea (DMU)–NH4Cl was found to be an
inexpensive, non-toxic, easily biodegradable and effective reaction medium in the catalyst …

In this paper, we developed a rhodium-catalyzed annulation of vinylene carbonate with
amidines, leading to 4-methylquinazolines with moderate to excellent yields. This procedure …

Three series of novel and new fused heterocyclic systems, viz. triazolo [4, 3-a]-quinazolin-7-
ones (4),[1, 2, 4, 5]-tetrazino [4, 3-a]-quinazolin-8-ones (6) and indolo [2, 3-c][1, 2, 4]-triazino …

This communication describes a catalyst‐free synthesis of 2‐substituted quinazolines and
4H‐benzo [d][1, 3] oxazines using commericially available sodium hypochlorite as oxidant …

A wide range of biologically active compounds contain the quinazoline ring system. A new
free-radical-based method of making functionalized quinazolines is described, which relies …

Quinazolines are a privileged class of nitrogen-containing heterocycles, widely present in a
variety of natural products and synthetic chemicals with a broad spectrum of biological and …

Microwave irradiation (MWI), as a unique, effective, sustainable, more economic, and
greener source of energy compared to conventional heating, is applied in different organic …

An efficient one-pot approach to multiple substituted quinazolines with diaryliodonium salt 1,
and two nitriles 2 has been presented. The reaction enables great flexibility of the …
