| 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 spiro[oxazolidine-2- thione-oxindoles] with 3-isothiocyanato oxindoles and aldehydes via a cascade aldol-cyclization. |
