Özet
Metallo-azomethine ylides, generated from iminophosphonates in combination with LiBr or AgOAc and bases Et3N, DBU, t-butyl tetramethylguanidine(BTMG) undergo cycloaddition to give dialkyl pyrrolidine-2-phosphonates along with the corresponding Michael adduct in some cases. Cycloadditions with the chiral dipolarophile 5R-(1'R,2'S,5'R-menthyloxy)-2-(5H)-furanone (MOF) afforded enantiopure cycloadducts.
