  The Influence of Inter- and Intramolecular Hydrogen Bonding upon the Structure and Photochemistry of 3-(2-Pyridyl)propenamides

  摘要：

  The molecular structures and photochemical behavior of (E)- and (Z)-N-methyl-3-(2-pyridyl)-propenamide have been investigated in the solid state and in solution. While the molecular conformation of the thermodynamically more stable E isomer is independent of phase or solvent, the conformation of the Z isomer is dependent upon its environment, adopting an s-trans intramolecular hydrogen-bonded conformation in chlorocarbon solvents, an s-cis conformation in methyl sulfoxide solution, and an orthogonal intermolecular hydrogen-bonded conformation in the solid state. The electronic structure of these molecules has been investigated using the semiemperical INDO/S-SCF-CI (ZINDO) algorithm. The two lowest energy adsorption bands are attributed to allowed pi --> pi* transitions; however, the existence of lower energy singlet n,pi* states is predicted. Neither isomer undergoes photoisomerization in the solid state. Photoisomerization of the E isomer is efficient in nonpolar solvents but occurs with decreased efficiency in solvents which are good hydrogen bond acceptors. The Z isomer undergoes photoisomerization only in strong hydrogen bond acceptor solvents which disrupt the intramolecular hydrogen bond. Thus, either inter- or intramolecular hydrogen bonding can influence the efficiency of photoisomerization. Similar results are obtained with several related N-substituted 3-(2-pyridyl)propenamides. These results provide the first example fo countrthermodynamic one-way E --> Z photoisomerization based upon intramolecular hydrogen bonding.

  5‐styryl‐oxathiazol‐2‐ones as inhibitors of the Mycobacterium tuberculosis (Mtb) proteasome. As part of the study, the structure–activity relationship of oxathiazolones as Mtb proteasome inhibitors has been investigated. Furthermore, the prepared compounds displayed a good selectivity profile for Mtb compared to the human proteasome. The 5‐styryl‐oxathiazol‐2‐one inhibitors identified showed little activity
