Título: | Cover Picture: Azomethine ylides from nitrones: Using catalytic nBuLi for the totally stereoselective synthesis of trans-2-alkyl-3-oxazolines (Chem. Eur. J. 33/2016) |

Fecha de publicación: | 2016 | Editor: | Wiley-VCH | Citación: | Chemistry - A European Journal 22(33): 11473 (2016) | Resumen: | A catalytic amount of nBuLi is enough for launching a catalytic cycle, in which a nitrone ylide reacts with an aldehyde through a two-step cycloaddition process to produce 3-oxazolines and a water molecule; the latter is used to regenerate the catalytic species. Actually, nBuLi acts as a pre-catalyst by forming initial activated reactants. Solvated lithium is not only the real catalyst of the reaction, but it is also responsible for water elimination.
