Published in 2019 at "Chemistry of Heterocyclic Compounds"

DOI: 10.1007/4746

Abstract: Reaction of 2-nitroacetophenone, furfurol, β-dicarbonyl compounds, and ammonium acetate led to 3-substituted 4-(2-furyl)-5-nitro-6-phenyl-1,4-dihydropyridines, which were oxidized with potassium nitrate in the presence of copper(II) nitrate (10 mol %), leading to the respective 5-nitro-6-phenylpyridines. The performed… read more here.

Published in 2021 at "Organic letters"

DOI: 10.1021/acs.orglett.1c01955

Abstract: An expedient route to enantiopure, diastereomeric pyrrolopyrazinoquinazolinones was developed following the discovery of a domino quinazolinone rearrangement-intramolecular cyclization of N-H benzamidines. A Ugi-Mumm-Staudinger sequence employing an optically pure proline derivative gave quinazolinones that, upon N-Boc… read more here.
