Abstract
The asymmetric 1,3-dipolar cycloaddition of azomethine imines to homoallylic alcohols was achieved by utilizing diisopropyl (R,R)-tartrate as a chiral auxiliary to give the corresponding optically active trans-pyrazolidines with excellent regio-, diastereo-, and enantioselectivities. The catalytic use of diisopropyl (R,R)-tartrate was also effective in the presence of MgBr 2 .
