In accordance with density functional theory calculations (at the B3LYP/cc-pVDZ-PP level), pericyclic transition structures with a boat-like conformation and a stabilizing hydrogen bond can account for the unexpected stereoselectivity.engAccess to Pyrrolidine Imino Sugars via Tin(II)-Mediated Aldol Reactions of Bislactim Ethers: Synthesis of 2,5-Dideoxy-2,5-Imino-D-Glucitoljournal articleopen access10.1039/B810878A
