Amine-Catalyzed Cascade Reactions of Unprotected AldosesAn Operationally Simple Access to Defined Configured Stereotetrads or Stereopentads
No full textAn amine-catalyzed cascade reaction
of unprotected carbohydrates
with 1.3-diketones was elaborated. This cascade is based on a Knoevenagel
reaction/intramolecular ketalization/retro-aldol reaction. By application
of this operationally simple protocol, a direct access to optically
active stereopentads or stereotetrads is given. Rules of configurative
outcomes will be discussed
