Abstract
An efficient synthesis of unsubstituted and substituted amides based on the 6,8-dioxa-3-azabicyclo[3.2.1]octane scaffold is described. The reaction, carried out at 60 degrees C in the absence of solvent, is characterized by its mildness and ease of workup. A library of amides, was synthesized by combination of methyl esters 1-6 with various amines. In addition, the microwave-assisted automated synthesis of the library was compared with the above conventional parallel synthesis. Microwave synthesis significantly decreased the reaction time from hours to minutes.File in questo prodotto:
