Gold(I)-Catalyzed Intramolecular Hydroamination of Unactivated Terminal and Internal Alkenes with 2-Pyridones.

Journal Article

The cationic gold phosphine complex [(P1)Au(NCMe)]+ SbF6 - [P1 = P(t-Bu)2 o-biphenyl; 2] catalyzes the intramolecular hydroamination of 6-alkenyl-2-pyridones to form 1,6-carboannulated 2-pyridones in high yield. The hydroamination of 6-(γ-alkenyl)-2-pyridones was effective for monosubstituted and 1,1- and 1,2-disubstituted aliphatic alkenes, and the method was likewise effective for the hydroamination of 6-(δ-alkenyl)-2-pyridones. Spectroscopic analysis of mixtures of 6-(3-butenyl)-2-pyridone, (P1)AuCl, and AgSbF6 established the N-bound 2-hydroxypyridine complex [(P1)Au(NC6 H3 -2-OH-6-CH2 CH2 CH═CH2 )]+ SbF6 - as the catalyst resting state.
