Alkynylation of Mixed Acetals with Organotin Acetylides

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.
