Abstract

Copper-catalysed arylative ring-closing reactions of 2-alkynylphenylcarbamates and 2-alkynylphenylureas with diaryliodonium salts gave C, N-double-arylated benzoxazin-2-ones and C-arylated benzoxazin-2-amines, respectively, both bearing fully substituted exocyclic olefins. On the other hand, the palladium-catalysed arylative ring-closing reaction of 2-alkynylphenylcarbamates gave C-arylated 2,3-disubstituted indoles. [ABSTRACT FROM AUTHOR]
