Li, Tian-Ze; Xie, Jin; Jiang, Yu; Sha, Feng; Wu, Xin-Yan published the artcile< Enantioselective Vinylogous Michael/Cyclization Cascade Reaction of Acyclic β,γ-Unsaturated Amides with Isatylidene Malononitriles: Asymmetric Construction of Spirocyclic Oxindoles>, Application of C19H34O2, the main research area is enantioselective vinylogous Michael reaction cyclization cascade reaction; spirocyclic oxindole preparation unsaturated amide isatylidene malononitrile cascade reaction.
The first direct and enantioselective vinylogous Michael/cyclization cascade reaction between acyclic β,γ-unsaturated amides and isatylidene malononitriles has been developed. Optically active spirocyclic oxindoles have been obtained in good-to-excellent yields (84-96%) and enantioselectivity (79-97% ee) in the presence of 2 mol% (DHQD)2PYR [2,5-diphenyl-4,6-bis(9-O-dihydroquinyl)pyrimidine].
Advanced Synthesis & Catalysis published new progress about Cyclization. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Application of C19H34O2.
