Technical Notes:
1.Michael Addition- highly enantioselective catalysts for the Michael addition of a-substituted cyanoacetates to vinyl sulfones, giving an efficient protocol for the construction of an all-carbon substituted quaternary
stereocentre.
2.Asymmetric catalysis of chiral oxindoles bearing 3-position all-carbon quaternary stereocenters.
3.The enantioselective Michael addition of dialkyl phosphites to N-unprotected isatylidene malononitriles .
4.Aldol Reaction- The first example of a direct catalytic asymmetric intermolecular aldol reaction of 3-
isothiocyanato oxindoles to simple ketones.
5.Cascade Aldol-Cyclization- A highly efficient method for the construction of a family of spirooxazolidine-2- thione-oxindoleswith 3-isothiocyanato oxindoles and aldehydes via a cascade aldol-cyclization.
