The author of the article were Singh, Priyanka; Kaur, Navpreet; Banerjee, Prabal. The article conveys some information:
A highly regioselective synthesis of tetrahydropyrrolo[1,2-a]quinazolin-5(1H)one derivatives was achieved by reacting cyclopropane aldehydes with N’-aryl anthranil hydrazides in the presence of p-toluenesulfonic acid (PTSA). The transformation involves domino imine formation and intramol. cyclization to form 2-arylcyclopropyl-2,3-dihydroquinazolin-4(1H)-one, followed by nucleophilic ring opening of the cyclopropyl ring to form desired tetrahydropyrrolo[1,2-a]quinazolin-5(1H)one in good to excellent yield with complete regioselectivity. This protocol tolerates a great variety of functional groups and thus provides a simple and step-efficient method for pyrroloquinazolinone synthesis. In the part of experimental materials, we found many familiar compounds, such as Trimethylsulfoxonium iodide(cas: 1774-47-6Application In Synthesis of Trimethylsulfoxonium iodide)
Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry. It is used to prepare ylide, which reacts with carbonyl compounds to get epoxides. Further, it reacts with alfa,beta-unsaturated esters to get cyclopropyl esters.Application In Synthesis of Trimethylsulfoxonium iodide
