Synthesis of 1′,2′-cis-Nucleoside analogues: Evidence of stereoelectronic control for SN2 reactions at the anomeric center of furanosides

We are reporting a highly diastereoselective route to 1′,2′- cis-nucleoside analogues in the d-ribo, d-lyxo, d-xylo, and d-arabinoside series. Five-membered ring lactols undergo highly selective N-glycosidation reactions in the presence of dimethylboron bromide with different silylated nucleobases. Stereoelectronic control plays a crucial role for the observed induction, and the products are proposed to be formed through SN2 "exploded" transition states. This approach shows great potential considering its simplicity and selectivity for the synthesis of nucleoside analogues, an important class of molecules in medicinal chemistry.

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.
