Abstract: ABSTRACT The sulphonic acid-functionalized Wang resin (Wang-OSO3H) was explored as a polymeric and recoverable acidic catalyst for the synthesis of isoindolo[2,1-a]quinazoline-5,11-dione derivatives under green conditions. Thus the Wang-OSO3H catalyzed MCR of isatoic anhydride, 2-formylbenzoic acid… read more here.

Abstract: Abstract A tandem cyclization reaction of diethyl 2-(2-aminobenzamido)malonates and 2-bromobenzaldehydes was developed for the synthesis of isoindolo[1,2-b]quinazoline derivatives. The quinazoline was formed first catalyzed by CuI, followed by a noteworthy α-arylation reaction under Pd and… read more here.
