2H-azirine 3-phosphonates: a new class of chiral iminodienophiles. Asymmetric synthesis of quaternary piperidine phosphonates

, 2002
Diels−Alder reactions of enantiomerically enriched 2H-azirine 3-phosphonates and dienes stereoselectively furnish optically pure, bicyclic aziridine adducts that on hydrogenation afford the first examples of enantiopure quaternary piperidine ...
