Asymmetric 1,3-dipolar cycloaddition reaction of azomethine imines to allyl alcohol
The asymmetric 1,3-dipolar cycloaddition of azomethine imines to allyl alcohol was achieved by utilizing diisopropyl (R,R)-tartrate as a chiral auxiliary to afford the corresponding optically active trans-pyrazolidines with excellent regio-, diastereo-, and enantioselectivities.
