, p. 6334 - 6342 (2021)
Alkynyl C-nucleosides are of high value for various applications; however, their synthesis remains underexplored. Here we report a simple route toward the synthesis of alkynyl C-nucleosides from simple and stable furanosyl carboxylic acids and terminal alkynes under low-cost and nontoxic copper catalysis. The approach that we report here demonstrates the power of Cu/photoredox dual catalysis to access highly complex glycosides under mild conditions.

The highly stereoselective synthesis of diverse medicinally valuable alkynyl C-glycosides under mild and green reaction conditions remains a great challenge. Herein, we wish to report a visible-light induced photocatalytic decarboxylative alkynylation app

The stereoselective access to original polyhydroxylated tetrahydropyranopyrroles is described. The key steps involve an inverse-demand Diels-Alder reaction and a ring contraction of a pyridazine heterocycle. Georg Thieme Verlag Stuttgart.

The efficient synthesis of novel polyhydroxy-tetrahydropyrano-pyrroles from acetylenic carbohydrate precursors in three to four steps is described. The methodology involves, as key steps, the ring contraction of pyridazine intermediates obtained by an inv

Reaction of halo acetals containing O, N, or S heteroatoms with tri-n-butyltin acetylides in the presence of ZnCl2 in CCl4 leads to the formation of α-alkynyl ethers, amines, and sulfides in good yields.The methodology is exemplified with the synthesis of amino acids and C-glycosides.
