The present invention relates to certain substituted phenyl oxazolidinones and to processes for the synthesis of the same. This invention also relates to pharmaceutical compositions containing the compounds of the present invention as antimicrobials. The compounds are useful antimicrobial agents, effective against a number of human and veterinary pathogens, including gram-positive aerobic bacteria, for example, multiple-resistant staphylococci, streptococci and enterococci as well as anaerobic organisms, for example, Bacterioides spp. and Clostridia spp. species, and acid fast organisms, for example, Mycobacterium tuberculosis, Mycobacterium avium and Mycobacterium spp.

identified that enables their transformation into imides and amides. The reaction proceeds by dual acylation of amidines via oxidative C(CO)–C(CO) bond cleavage of 1,2-diketones to afford N,N′-diaroyl-N-arylbenzamidine intermediates. In the reaction, these intermediates are easily hydrolyzed into imides and amides through vanadium catalysis. This method provides a practical, simple, and mild synthetic

Bz-I and 2Pyr-I, the primary hydrogenbonding resembled that of the other members of the family, indicating that the interactions mediated via the iodine atom were complementary to rather than competitive with the hydrogen bonds. Two polymorphs of 4Pyr-I were found, and in both forms, a halogenbond was formed with the N(py) acceptor which was engaged in N–H···N hydrogen bonds in the other members of

The present report outlines our efforts toward a simple yet elegant protocol for O-acylation of a wide variety of phenols. This highly enabling and solventless method relies on vinylacetate as an innocuous acyl donor and DABCO as an organocatalyst. Operational simplicity, excellent yields, higher and faster conversion rates without excess reagents, a simple workup and essentially no need of columns
