An efficient method was developed for the one-pot construction of pyrrolo[1,2-a]quinoxalines via a Cu(II)-catalyzed domino reaction between 2-(1H-pyrrol-1-yl)anilines and alkylsilyl peroxides.
A naturally derived organophotoredox catalyst system enables the metal-free, stereoselective ring-opening allylation of cyclobutanone O-acetyl oxime esters under mild conditions.
A copper-catalyzed cyanoalkyl-alkynylation of gem-disubstituted alkenes has been established, which provides an efficient and valuable method for constructing alkynyl all-carbon quaternary center compounds under mild reaction conditions.
A palladium-catalyzed regioselective hydrocarbofunctionalization of nonconjugated alkenes for the synthesis of azaarenes possessing a fluorine-bearing quaternary carbon center is described.
Efficient C–C bond cleavage is recognized as a persistent challenge in the field of synthetic methodology. In this paper, we found that tert-alkylated cyclohexadienones are good tert-alkyl radical donors in the presence of photocatalysts and that olefination with enamides proceeds.
