Jiang, Ben-Jie published the artcileSynthesis of Quinolines and 2-Functionalized Quinolines by Difluorocarbene Incorporation, Product Details of C7H6N2, the main research area is functionalized quinoline chemoselective preparation; quinoline preparation.
A general method was developed to allow de novo construction of quinolines I [R = Me, cyclopropyl, Ph, etc.] and C2-functionalized quinolines II [R1 = Me, cyclopentyl, Ph; R2 = Ph, Bn, 1-naphthyl, etc.; R3 = H, Me] from ortho-alkenyl anilines in the presence of a difluorocarbene precursor. This method exploited a crucial reactivity of in-situ generation of isocyanides from condensation of primary aniline with difluorocarbene. Subsequent α-addition of isocyanide by neighboring alkenyl group constructs the quinoline ring. Furthermore, when a combination of difluorocarbene precursor and Se are present, selenoisocyanate intermediates were tentatively generated that upon nucleophilic addition by ortho-alkenyl produce 2-SeH quinolines. In the presence of a second nucleophile such as anilines, competing nucleophilic addition of anilines to the selenoisocyanate was preferred, generating selenourea intermediate. Further nucleophilic addition of the ortho-alkenyl to selenourea followed by elimination of H2Se produces 2-aminoquinolines. This allows one-step multi-component modular preparation of various C2-functionalized quinolines from readily available starting compounds This method showed good yields, scope and chemoselectivity. It was operationally convenient and friendly without manipulating unpleasant isocyanides. The difluorocarbene-enabled primary amine to isocyanide conversion may be exploited to develop other interesting reactions.
