A visible light-enabled cascade cyclization strategy is disclosed with concomitant phosphorylation and heterocycle construction. It provides a novel environmentally benign approach for accessing tetrahydroindolizine-containing phosphonates under metal-free conditions. Mechanistic studies revealed that phosphinoyl radicals were generated from H-phosphonates via HAT process.

New photochemical approaches to 2,3-fused quinazolinones and dihydroquinazolinones are disclosed. The intramolecular hydrocyclization proceeds in moderate excellent yields across diverse alkenes with high regioselectivity diastereocontrol. Mechanistic studies indicated that the radical cascade processes involve thiophenol acting as single-electron transfer hydrogen atom reagents. success of gram-scale synthesis proves strategy can be used for practical applications.

Abstract The synthesis of acylmethylatated pyrrolo‐quinazolinones was developed via photo‐induced cascade radical addition/cyclization N ‐(but‐3‐enyl)quinazolin‐4(3 H )‐ones with sulfoxonium ylides using 4CzIPN as the photocatalyst. This approach also suitable for construction piperidino‐quinazolinones. protocol features mild conditions, convenient operation, broad substrate scope and good functional group compatibility.
