ABSTRACT:
The invention relates to an efficient and facile method for the preparation of substituted lactams, as described herein. The method comprises reacting a difunctional component containing an activated carbon, an amine capable of forming an imine with the activated carbon of the difunctional component, and an isocyanide in a nucleophilic polar protic solvent and at a concentration of reactants which facilitates the formation of the substituted lactams. The invention also relates to novel substituted lactams, libraries comprising such lactams, and a method of generating libraries substituted lactams, using the method of the invention.
