Öğe New zinc(II)-based catalyst for asymmetric azomethine ylide cycloaddition reactions(Amer Chemical Soc, 2006) Doğan, Özdemir; Koyuncu, Hasan; Garner, Philip; Bulut, Adnan; Youngs, Wiley J.; Panzner, MatthewA new chiral aziridino alcohol ligand for zinc(II)-catalyzed azomethine ylide cycloadditions is described. In the presence of this catalyst, N-arylidene glycine methyl esters react with a variety of dipolarophiles to give substituted pyrrolidines in very good to excellent chemical yields and up to 95% ee. The absolute sense of asymmetric induction appears to be dipolarophile-dependent.
