A route for synthesizing novel C-nucleosides with 3,6- and 3,5,6-substituted pyridazines as heterocyclic aglycones is described. [4+2]-Cycloadditions of the alkyne substituted precursors 1 and 10a-d with the 1,2,4,5-tetrazines 2a,b, containing a highly re

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.
