On October 1, 2010, Peng, Jing; Huang, Xin; Cui, Hai-Lei; Chen, Ying-Chun published an article.SDS of cas: 2510-01-2 The title of the article was Organocatalytic and Electrophilic Approach to Oxindoles with C3-Quaternary Stereocenters. And the article contained the following:
A Lewis base-catalyzed asym. allylic alkylation of Morita-Baylis-Hillman carbonates derived from isatins has been investigated, which provides an electrophilic pathway to access oxindoles, e.g. I, bearing C3-quaternary stereocenters. Excellent diastereoselectivity and high enantioselectivity have been obtained in the vinylogous functionalization of α,α-dicyanoolefin nucleophiles, giving multifunctional products with vicinal quaternary and tertiary chiral carbon centers. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).SDS of cas: 2510-01-2
The Article related to organocatalytic electrophilic oxindole preparation enantioselective diastereoselective allylic alkylation, spirocyclic oxindole preparation diastereoselective enantioselective intramol michael addition cyclization, lewis base catalyst allylic alkylation dicyanoolefin oxindole carbonate reactant, quaternary oxindole preparation stereoselective allylic alkylation and other aspects.SDS of cas: 2510-01-2
