A unified strategy for the synthesis of 2-vinyl heterocycles is reported. With visible light irradiation, simple and cheap CuCl is able to functionalize a terminal alkyne, giving Cu(I)-acetylide in situ. Unlike the case of noble metals or organic dye photocatalysts, this critical Cu(I)-acetylide not only activates the C-H bond of terminal alkynes but also serves as a photocatalyst to achieve varieties of 2-vinyl heterocycles in good to excellent yields, even for large scale and late-stage functionalization of natural product.
Tandem Peterson-Michael reaction using α-silylalkylphosphine chalcogenides and Horner-Emmons reaction of in situ generated α-carbanions of its products

Title tandem reaction was achieved by using α-(trimethylsilyl)-alkylphosphine chalcogenides and the lithio derivative of 2-hydroxytetrahydropyran. The Horner-Emmons reaction of the tandem products was accomplished to give the corresponding 2-(β-styryl)tet
DIRECT SUBSTITUTION OF 2-BENZENESULPHONYL CYCLIC ETHERS USING ORGANOZINC REAGENTS
Brown, Dearg S.,Ley, Steven V.
, p. 4869 - 4872 (2007/10/02)
2-Benzenesulphonyl cycle ethers are converted in good yield at room temperature to the 2-aryl-, 2-alkenyl or 2-alkynyl product by treatment with the corresponding organozinc species.
