  Densely Functionalized Chiral Pyrroles from Endocyclic, Exocyclic, and Acyclic Vinyl Sulfone-Modified Carbohydrates

  摘要：

  A wide range of vinyl sulfone-modified carbohydrates have been prepared as starting materials for the synthesis of polysubstituted chiral pyrroles. All these vinyl sulfones reacted efficiently with ethylisocyanoacetate to generate a plethora of new pyrrole derivatives. Furanosyl rings opened up during pyrrole synthesis, and pyranosyl rings were opened up by reacting the pyrrole with POCl3/DMF. This paper also reports one of the most efficient and practical routes for the synthesis of beta-substituted pyrroles.
