Liang, Qi; Lin, Long; Li, Guodong; Kong, Xianqiang; Xu, Bo published the artcile< Synthesis of Phenanthridine and Quinoxaline Derivatives via Copper-Catalyzed Radical Cyanoalkylation of Cyclobutanone Oxime Esters and Vinyl Azides>, Application of C19H34O2, the main research area is cyanoalkyl phenanthridine quinoxaline spiro compound preparation; cyclobutanone oxime ester vinyl azide radical cyanoalkylation copper catalyst.
A copper-catalyzed radical cyclization of cyclobutanone oxime esters and vinyl azide is described. This method provides facile access to cyanoalkyl-substituted phenanthridines I (R1 = H, 1-OMe, 3-Cl, etc; R2 = H, 8-CF3, 9-Me, etc.; R3 = H, CN, Ph, etc.) and quinoxalines II (R3 = H, COOMe, OBn, etc.; R4 = H, 8-Me, 7-Br, etc.) with excellent isolated yields. Moreover, these reactions proceed under mild conditions with a board substrate scope and excellent functional group tolerance.
Chinese Journal of Chemistry published new progress about Alkylation catalysts (cyano-). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Application of C19H34O2.
