1,3-Dipolar cycloadditions of 9-diazofluorenes with 2-acyl-2H-1,2,3- diazaphospholes to synthesise phosphiranes and trimers

A series of 2-acyl-2H-1,2,3-diazaphospholes underwent readily 1,3-dipolar cycloaddition reactions with 9-diazofluorenes as the 1,3-dipole, yielding the respective bicyclic phosphiranes or trimers depending on the reaction conditions employed.

Synthesis of 9-acetyl-8,9-diaza-1-phosphabicyclo[4.3.0]nona-3,7-dienes by regioselective Diels-Alder reaction of 2H-1,2,3-diazaphospholes with isoprene

2H-1,2,3-Diazaphospholes, prepared from various hydrazones and phosphorus trichloride in the presence of triethylamine, react with isoprene to give highly regioselective Diels-Alder products in good yield.
