Hydrostannylation-cross-coupling strategy for the stereoselective synthesis of alkylidenemalonates and related α,β-unsaturated esters

A method for the stereoselective synthesis of alkylidenemalonates and related α,β-unsaturated esters by a hydrostannylation-cross-coupling process has been developed. Pd-catalyzed and radical hydrostannylation of propiolate derivatives stereoselectively provided α-alkoxycarbonyl (E)- and (Z)-vinylstannanes, respectively, which were then converted into alkylidenemalonates by the Stille coupling reaction. A one-pot process was also realizable for the Pd-catalyzed reactions.

Room temperature palladium catalysed coupling of acyl chlorides with terminal alkynes

Conditions are reported for the facile, high-yielding coupling of acyl chlorides with terminal alkynes in a reaction involving palladium and copper iodide; the reaction is tolerant of a wide variety of acyl chlorides and terminal alkynes and provides a co
