Gold carbene reactivity patterns were accessed by ynamide insertion into a C(sp3)-H bond. A substantial increase in molecular complexity occurred through the cascade polycyclization of N-allyl ynamides to form fused nitrogen-heterocycle scaffol

The selective syntheses of 1- and 2-indan-one compounds from 2-ethynylbenzyl ethers have been achieved with suitable catalysts and solvents. The highly acidic [tris(pentafluorophenyl)phos-phine]gold hexafluoroantimonate [(C6F5)3AuSbF6] in nitromethane (MeNO2) preferably gives 1-indan-ones whereas [(ortho-biphenyl) di(tert-butyl)phosphine] gold triflimide [(tBu)2(o-biphenyl) AuNTf2] in dichloroethane tends to form 2-indanone derivatives. For 2-indanone products, we isolated two indenyl methyl ethers for deuterium labeling analyses, providing evidence for p-alkyne activation.
