General description

This vinylstannane undergoes Stille coupling with a vinyl triflate, giving, after hydrolysis, an α,β−unsaturated ketone, thus acting as an acetyl anion equivalent.

Application

Electrophilic methyl ketone equivalent used in a recent synthesis of a 13-oxophorbine (chlorophyll) from the corresponding 13-bromochlorin.
Reagent employed in palladium-catalyzed coupling reactions with sulfoxides, α-haloethers, and chlorocyclobutenones. Also used to convert acid chlorides to α-oxygenated enones.

2-Azabicyclo[2.2.2]oct-5-enes bearing an endo alkenyl substituent were synthesized by Diels-Alder addition of methyl vinyl ketone to a 1,6-dihydropyridine derived from methyl nicotinate. Although 1,5-dienes with this skeleton were unreactive under thermal conditions, they were photochemically reactive. Irradiation of these dienes

A new route to 13(1)-oxophorbines, the parent macrocycle of chlorophylls, begins with the synthesis of a 13-bromochlorin. Pd-mediated coupling of the latter with tributyl(1-ethoxyvinyl)tin and subsequent acidic hydrolysis afforded the 13-acetylchlorin (1). Treatment of 1 with NBS afforded the 15-bromo
