Gold-catalyzed nitrene transfer to activated alkynes: formation of α,β-unsaturated amidines.
Organic letters 20110225 7
A gold-catalyzed intermolecular nitrene transfer to alkynes was developed for the first time, revealing a new mode of nitrene transfer and providing a novel access to versatile α-imino metal carbenes. Various mild nitrene-transfer reagents were examined, and iminopyridium ylides especially those based on 3,5-dichloropyridine proved be highly effective. With activated alkynes such as N-alkynyloxazolidinones as substrates, α,β-unsaturated amidines were formed in mostly good yields. ...[more]
