Intermolecular enolate heterocoupling: Scope, mechanism, and application

This full account presents the background on, discovery of, and extensive insight that has been gained into the oxidative intermolecular coupling of two different carbonyl species. Optimization of this process has culminated in reliable and scalable proto

NOVEL HYDROXAMIC ACID DERIVATIVES

Disclosed are compounds which have not only potent metalloproteinase-inhibiting activity but also amazingly excellent bioavailability and biological activity invivo, including the property of being well absorbed via oral routes, thereby serving as useful pharmaceuticals, intermediates and processes for the production thereof. The disclosed compounds of the formula (I): wherein R1 is hydrogen, or a hydroxy-protecting group; R2 is hydrogen, or an amino-protecting group; R3, R7, and R8, which may be identical or different, are each independently hydrogen, hydroxy, unsubstituted or optionally substituted (C1-C6) alkyl, or unsubstituted or optionally substituted aryl-(C1-C6) alkyl; R4 is unsubstituted or optionally substituted (C1-C6) alkyl, or unsubstituted or optionally substituted aryl-(C1-C6) alkyl; R5 is hydrogen, unsubstituted or optionally substituted alkyl, unsubstituted or optionally substituted aralkyl, or a carboxy-protecting group; R6 is hydrogen, hydroxy, amino, and a group of the formula: -X-Y wherein X is oxygen, (C1-C6) alkylene or phenylene, Y is a group of the formula: -A-B or -B, wherein A is (C1-C6) alkylene, imino, and (C1-C6) alkyleneimino, and B is hydrogen, amino, amidino, sulfonyl, acylimidoyl, unsubstituted or optionally substituted imidazolyl, unprotected or optionally protected bis(phosphono)methyl or unprotected or optionally protected bis(phosphono)hydroxymethyl; or salts thereof are useful for pharmaceutical and/or veterinary compositions, particularly as metalloproteinase inhibitors which inhibit matrix metalloproteinases or tumor necrosis factor-α-converting enzymes (TNF-α convertases).
