摘要
H-1,2,3-Diazaphospholes 3a3h were prepared from various ketone acylhydrazones and phosphorus trichlo-ride in the presence of triethylamine. Compounds 3 underwent feasible hetero-Diels-Alder reactions with cyclopen-tadiene to afford the respective anellated [1,2,3]diazaphospholes 4a4d as well as 4a'4d' in moderate yields. The endo rule in the reaction was observed under kinetic control conditions.
