Syntheses of α-pyrones using gold-catalyzed coupling reactions
Luo, Tuoping,Dai, Mingji,Zheng, Shao-Liang,Schreiber, Stuart L.
supporting information; experimental part, p. 2834 - 2836 (2011/07/07)
Sequential alkyne activation of terminal alkynes and propiolic acids by gold(I) catalysts yields compounds having α-pyrone skeletons. Novel cascade reactions involving propiolic acids are reported that give rise to α-pyrones with different substitution patterns.
Regio- and stereoselective preparation of γ-alkylidenebutenolides or α-pyrones using a Stille reaction and palladium-catalysed oxacyclisation sequence
Rousset, Séverine,Abarbri, Mohamed,Thibonnet, Jér?me,Parrain, Jean-Luc,Duchêne, Alain

Synthesis of butenolides or α-pyrones from substituted tributylstannyl acetylides is highly dependant on the nature of the acetylide.
