DOI: 10.1016/j.mcat.2020.111345

Abstract: Abstract Herein, an environmentally benign electrochemical protocol has been disclosed for the synthesis of quinazolin-4(3H)-one derivatives from readily available α‑keto acids and 2-aminobenzamides. This decarboxylative cyclization process proceeds conveniently in the absence of any homogeneous… read more here.

Published in 2017 at "Tetrahedron Letters"

DOI: 10.1016/j.tetlet.2016.12.079

Abstract: An efficient and practical method was developed for the synthesis of tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones based on the decarboxylative cyclization reaction of α-ketoamides and proline. In most cases, tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones were obtained with perfect diastereoselectivity to give trans-isomer in… read more here.

Abstract: A silver-catalyzed decarboxylative cyclization process has been developed for the synthesis of substituted pyrazoles from the readily available 1,2-diaza-1,3-dienes and α-keto acids. Under the optimized conditions, a series of multisubstituted pyrazoles were well prepared in… read more here.
