experimental part, p. 2872 - 2874 (2010/04/02)
The asymmetric synthesis of ,-disubstituted -bisalkoxycarbonyl sulfonates is reported. The synthesis is based on the Michael addition of a lithiated enantiopure sulfonate bearing a cheap chiral sugar auxiliary to Knoevenagel acceptors. The reaction procee
