, p. 2676 - 2680 (2013/01/15)
Binaphthyl sulfonimides have been developed to catalyze the asymmetric Michael addition of ketone to alkylidene malonates, affording the corresponding Michael products in good to high yields (up to 98%) with good to excellent diastereoselectivity (up to 9

supporting information; experimental part, p. 2062 - 2066 (2010/06/15)
Pyrrolidinyl-camphor derivatives have been proven to be efficient organocatalysts for enantioselective conjugate addition of ketones to alkylidene malonates, affording high chemical yields (up to 95 %) of the corresponding products with high to excellent levels of diastereoselectivity (up to >99:1 dr) and enantioselectivity (up to 96%ee) under solvent-free reaction conditions at ambient temperature.
