Abstract
Article history: Received December 15, 2011 Received in Revised form January 1, 2012 Accepted 1 January 2012 Available online 16 January 2012 A simple and economic synthesis of 3,4-dihydropyrimidin-2(1H)-ones using pyridinium triflate as catalyst under microwave condition was attempted with an easy work-up protocol. Further tetrazolo [1,5-a] pyrimidine-6-carboxylates were synthesized by three-component coupling reaction of β-ketoesters with a mixture of aromatic aldehyde and 5-aminotetrazole. The products were well characterized with IR, NMR (1H and 13C NMR) and mass spectrometry. © 2012 Growing Science Ltd. All rights reserved.
