On April 28, 2007, Niess, Barbara; Joergensen, Karl Anker published an article.Recommanded Product: 2510-01-2 The title of the article was The asymmetric vinylogous Mannich reaction of dicyanoalkylidenes with α-amido sulfones under phase-transfer conditions. And the article contained the following:
The stereoselective vinylogous Mannich reaction of dicyanoalkylidenes under phase-transfer catalytic conditions utilizing stable α-amido sulfones as imine precursors is presented; a rigid pyrrolidinium salt acts as the phase-transfer catalyst, giving access to the amino alkylated products, e.g., I, in generally good yield and up to 95% ee. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Recommanded Product: 2510-01-2
The Article related to amido sulfone dicyanoalkylidene chiral pyrrolidinium asym vinylogous mannich, aminoalkyl unsaturated dinitrile stereoselective preparation, asym vinylogous mannich phase transfer catalyst chiral pyrrolidinium and other aspects.Recommanded Product: 2510-01-2
