Page/Page column 40; 41, (2019/10/04)
The present invention is directed to new pyridinone or pyrimidinone hydroxamic acid phosphates of Formula (1 ) and boronates of Formula (2), stereoisomers thereof; wherein Q is selected from the group consisting of -P(0)(OH)2, -P(0)(OH)(0"M+), - P(0)(0"M+)2 and -P(0)(0")2M2+; M+ at each occurrence is a pharmaceutically acceptable monovalent cation; and M2+ is a pharmaceutically acceptable divalent cation; X is CH or N; and Z is as defined herein; and their use as LpxC inhibitors and, more specifically, their use to treat bacterial infections.

The synthesis of three 1D coordination polymers (CPs), [Zn(TPPZ)(HCCB)]n·DMF·H2O (1) [Cd(TPPZ)(HCCB)]n(2) and [Co(TPPZ)(HCCB)]n(3), based on the N,N,N-chelating κ3-2,3,5,6-tetrakis(2-pyridyl)pyrazine (TPPZ) and polymerizing carboxylate (–COO?) 3-(carboxy-methylamino)-4-chlorobenzoic acid (H3CCB) ligands, using a solvothermal method, have been described. The CPs have been adequately characterized by satisfactory elemental analyses, FT-IR, UV–vis, emission, TGA and PXRD analysis. The structure of 1 has been verified by single crystal X-ray diffraction analysis. The structural data revealed the 5-coordinated heteroleptic polymeric framework is exclusively extended through the H3CCB carboxylate group and strong N,N,N-chelating TPPZ ligand acts as a branch terminating site. Notably, the structure of 1 is comprised of one unit of each H2O and DMF solvent in its crystal lattice. In contrast, 2 and 3 exclude lattice solvents, as suggested by PXRD studies, after thermal desolvation of 1. Furthermore, 1 with 5-coordinated Zn(II) centers exhibited an efficient catalytic performance for transesterification reactions, with remarkable stability and good reusability.

A scandium triflate (ScOTf)3 catalyzed methodology has been developed to synthesize esters from primary amides. Various primary and secondary aliphatic alcohols have been shown to react in n-heptane with a range of primary amides for 24 h.
