资源简介：
A Ru(II)-catalyzed
facile and controllable protocol for C–H
alkylation and spirocyclization of 2-arylquinoxalines with maleimides
has been achieved under ambient air in high yields. Sequential ortho-C–H
activation and C-annulation results in the formation
of diverse polyheterocycles containing spiro[indeno[1,2-b]quinoxaline-11,3′-pyrrolidine]-2′,5′-diones,
which are of potent interest in medicinal chemistry. Mechanistic investigations
suggest a reversible cleavage of the ortho-C–H bond in the
turnover-limiting step.
