A ligand-free palladium-catalyzed aerobic oxidative carbonylation of amines for the synthesis of ureas, particular unsymmetrically N,N′-disubstituted ureas, which cannot be accessed by any other palladium-catalyzed oxidative carbonylation of amines to date, is presented. An array of symmetrical and unsymmetrical ureas were straightforwardly synthesized by using inexpensive, readily available, stable

series of 2-[4-[[[(substituted-phenyl)amino]carbonyl]amino]phenoxy]-2- methylpropionic acids and other substituted phenoxyacetic acids were synthesized and tested for their ability to reduce the affinity of hemoglobin for oxygen. 2-[4-[[[(3,4,5-trichlorophenyl)amino]carbonyl]amino]phenoxy]-2- methylpropionic acid was found to be the most potent compound known. Structure-activityrelationships of the compounds

The present invention relates to newer generation of triazoles, tetrazoles, isoxazoles, urea and sulphonamide functionalities containing 6-nitro-2, 3-dihydronitroimidazooxazoles agents of formula 1, their method of preparation, and their use as drugs for treating
Mycobacterium tuberculosis
, MDR-TB and XDR-TB either alone or in combination with other anti-tubercular agents. In the present invention, new generation 6-nitro-2, 3-dihydronitroimidazooxazoles agents also show acceptable pharmacokinetic properties and synergistic or additive effects with known anti-tubercular drugs.
