Simple and straight forward synthesis of 2,4-disubstituted quinazolines in aqueous medium

Efficient synthesis of diverse quinazolines from readily available starting materials was achieved in aqueous medium via one-pot protocol. A number of 2,4-disubstituted quinazolines were prepared in moderate to good yields under mild and catalyst-free conditions. Neutral reaction conditions, easy work-up procedures with wide substrate scope and atom economy are the remarkable features of this method

Biomimetic Synthesis of Quinoxalines in Water

Various quinoxalines have been synthesized for the first time in the presence of β-cyclodextrin in water. Biomimetic catalysis of β-cyclodextrin is explained by using 1H NMR spectroscopy. © 2009 Elsevier Ltd. All rights reserved
