3.Enantioselective alkynylation of benzoel[1,2,3- oxathiazine 2,2 dioxides catalysed by (R)-VAPOL -Zn complexes - synthesis of chiral propargylic cyclic sulfamidates.

4. Chiral boron complex-promoted asymmetric Diels Alder cycloaddition and its application in natural product synthesis.

5.Enantioselective addition of Et2Zn to seven membered cyclic imines catalyzed by a (R)-VAPOL -Zn(I) complex.

6.Catalyst-Coatrolled multicomponent . an L aziridination of chiral aldehydes
