Synthesis of heteroannulated indolopyrazines through domino N-H palladium-catalyzed/metal-free oxidative C-H bond activation / Y. A. Kvashnin, E. V. Verbitskiy, E. F. Zhilina [et al.] // ACS Omega. - 2020. - Vol. 5, № 25. - P15681-15690 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A convenient approach to [1,2,5]oxadiazolo[3′,4′:5,6]pyrazino[2,3-b]indoles and their heteroannulated analogues bearing various aryl substituents in the backbone has been developed. This synthetic protocol is based on Pd-catalyzed Buchwald–Hartwig and subsequent annulation by intramolecular oxidative cyclodehydrogenation. The photophysical properties for new polycycles have been measured. |
