“…1,2,3-Diazaphospholes are well-known and have been intensively studied by many chemists . Organophosphorus compounds are important naturally occurring substrates in several biochemical processes, and tetracoordinated pentavalent phosphorus compounds are well-known biologically active compounds that possess potent anticholinesterase activity .…”

“…1,2,3-Diazaphospholes and 1,2,3-diazaphospholines can usually be synthesized by the reaction of hydrazones with PCl 3 [2][3][4][5][6][7][8][9] or phenyldibromophosphine. 10 However, most of these studies were confined to substituted 1,2,3-diazaphospholes, and only little was conducted on polycyclic 1,2,3-diazaphosphole derivatives.…”

“…10 However, most of these studies were confined to substituted 1,2,3-diazaphospholes, and only little was conducted on polycyclic 1,2,3-diazaphosphole derivatives. 3,10 According to the reported procedure, [2][3][4][5][6][7][8][9] our attempt to synthesize 4-arylchromeno [3,4-d][1,2,3]diazaphospholes by the reaction of 2-phenylchromone-4-semicarbazone (1a) with PCl 3 was unsuccessful. We accidentally found that diazaphosphole derivative 2a could be obtained via the reaction of 1a with excess POCl 3 (used as a solvent) and SOCl 2 , followed by treatment with ethanol (Scheme 1).…”
