A controlled selective synthesis of dihydropyrans through tandem reaction of alkynes with diazo compounds

We report here an effective protocol to prepare highly functionalized dihydropyrans via sequential reaction of cross-coupling-intramolecular Michael addition of functionalized terminal alkynes and diazo compounds under mild reaction conditions. Importantly, by choosing different ligands, the configuration of exocyclic double bonds of dihydropyrans can be selectively controlled.

Yb(OTf)3-promoted ZnCl2-catalyzed conia-ene reaction of linear β-alkynic β-dicarbonyls

An atom-economical and solvent-free ytterbium(III) triflate promoted, zinc(II) chloride catalyzed Conia-ene method has been developed for the construction of five- to six-membered-ring carbocycles. In the presence of zinc(II) chloride and ytterbium(III) triflate, a variety of linear β-alkynic β-keto esters and -alkynic -diketones were cyclized under neat conditions in moderate to good yields. It is noteworthy that the selectivity toward five- or six-membered-ring carbocycles depends on substituents at the terminal alkynes. Georg Thieme Verlag Stuttgart.

Copper/silver-cocatalyzed conia-ene reaction of linear β-alkynic β-ketoesters

A novel and general copper/silver catalytic system has been developed for the Conia-ene intramolecular reaction of linear β-alkynic β-ketoesters. In the presence of (CuOTf)2·C 6H6 and AgSbF6 (or AgOAc), a variety of the linear β-alkynic β-ketoesters selectively underwent the Conia-ene intramolecular reaction in moderate to good yields.
