This work describes gold-catalyzed additions of vinyldiazo ketones to N-(o-alkynylphenyl)imines to yield 3-(furan-2-ylmethyl)-1H-indoles involving skeletal rearrangement; these new catalytic reactions are applicable to a wide range of substrates. We postu

A Pt-catalyzed, highly regioselective reaction between N-allenamides and imino-alkynes leading to pyrrolo[1,2-a]indoles is described. This represents the first example of [3+2]-annulation of Pt-bound azomethine ylides with the distal C=C bond of N-allenam

Treatment of N-(o-alkynylphenyl)imine derivatives with W(CO)5(L) induces the 5-endo-mode of cyclization of the imine nitrogen onto the electrophilically activated alkyne moiety to afford a novel reactive species, a metal-containing azomethine ylide. [3 + 2] cycloaddition of this ylide species with various electron-rich alkenes proceeds smoothly to give unstable carbene complexes, which in turn undergo 1,2-hydrogen-, alkyl-, and aryl-migration to afford in good yield 6-5-5 tricyclic indole skeletons having an alkyl or an aryl substituent at the 3-position of the indole nucleus.
