Highly Site Selective Formal [5+2] and [4+2] Annulations of Isoxazoles with Heterosubstituted Alkynes by Platinum Catalysis: Rapid Access to Functionalized 1,3-Oxazepines and 2,5-Dihydropyridines

Platinum-catalyzed formal [5+2] and [4+2] annulations of isoxazoles with heterosubstituted alkynes enabled the atom-economical synthesis of valuable 1,3-oxazepines and 2,5-dihydropyridines, respectively. Importantly, this Pt catalysis not only led to unique reactivity dramatically divergent from that observed under Au catalysis, but also proceeded via unprecedented α-imino platinum carbene intermediates.

Alkoxyacetylenes from alkyl 1,2-dichlorovinyl ethers

Alkyl 1,2-dichlorovinyl ethers 4, prepared from sodium alkoxides 1 and trichloroethylene 2, react in tetrahydrofuran with two equivalents of butyllithium to afford lithium alkoxyacetylides 5. On the one hand, these acetylides react with ketones or dichlor
