ABSTRACT:
A method for the preparation of a compound of general Formula:or pharmaceutically acceptable derivatives and salts, racemates, isomers and/or tautomers thereof comprising cyclizing an azomethine ylide of general Formula:wherein,A is a cyclic or non-cyclic group; Z is a carbon or a heteroatom; n is selected from 0, 1, 2 or 3; W, X and Y may be the same or different and each are selected from hydrogen; optionally substituted alkyl, alkenyl, alkynyl, amino, alkoxy, alkenoxy, alkynoxy, aryl, alkylthio, heterocyclyl; carboxy, carboxy ester, carboxamido, acyl, acyloxy, mercapto, halogen, nitro, sulfate, phosphate, cyano and optionally protected hydroxy; or W and X, together with the nitrogen and carbon atoms to which they are attached, form a saturated or unsaturated nitrogen containing heterocyclic group which may be optionally substituted or optionally fused to a saturated or unsaturated carbocyclic group, aryl group or heterocyclic group is provided.
