PIFA-Promoted, Solvent-Controlled Selective Functionalization of C(sp2)-H or C(sp3)-H: Nitration via C-N Bond Cleavage of CH3NO2, Cyanation, or Oxygenation in Water

A novel nitration (via C(sp3)-N breaking/C(sp2)-N formation with CH3NO2) mediated by [bis(trifluoroacetoxy)iodo]benzene (PIFA) is described. The NO2 transfer from CH3NO2 to the aromatic group of the substrate is possible with careful selection of the solvent, NaX, and oxidant. In addition, the solvent-controlled C(sp2)-H functionalization can shift to an α-C(sp3)-H functionalization (cyanation or oxygenation) of the α-C(sp3)-H of cyclic amines.

OXAZOLIDINONE ANTIBIOTICS

The invention relates to compounds of formula (I) wherein U, V, W, X, R1, R2, R3, R4, R5, R6, A, B, D, E, G, m, and n are as defined in the description, to pharmaceutically acceptable salts of such compounds for use in the manufacture of a medicament for the prevention or treatment of a bacterial infection. Certain compounds of formula (I) are new and are also part of this invention.

CYCLOHEXYL OR PIPERIDINYL CARBOXAMIDE ANTIBIOTIC DERIVATIVES

The invention relates to antibiotic cyclohexyl or piperidinyl carboximide derivatives of formula (I) wherein R1 represents hydrogen, halogen, (C1-C4)alkyl, (C1-C4)alkoxy, cyano or COOR2, R2 being (C1-C4)alkyl;one or two of U, V, W and X represent(s) N and the remaining represent each CH, or, in the case of X, may also represent CRX, RX being a halogen atom;either B represents N and A represents CH2CH2 or CH(OR3)CH2, or B represents CH or C(OR4) and A represents OCH2, CH2CH(OR5), CH(OR6)CH2, CH(OR7)CH(OR8), CH═CH or CH2CH2;each of R3, R4, R5, R6, R7, and R8 represents independently hydrogen, SO3H, PO3H2, CH2OPO3H2 or COR9, R9 being either CH2CH2COOH or such that R9—COOH is naturally occurring amino acid or dimethylaminoglycine;and to salts of such compounds of formula (I).
