Disclosed herein are antimicrobial compounds compositions, pharmaceutical compositions, the use and preparation thereof. Some embodiments relate to imidazole, thiazole, and furan derivatives and their use as therapeutic agents.
N-Aryl and N-alkenyl carbamoyl benzotriazoles were prepared in good to excellent yields from acyl azides and benzotri-azole via Curtiusrearrangement, while N-alkylcarbamoyl benzotriazoles were formed from N-alkanoyl benzotriazoles and sodium azide in one pot. The carbamoyl benzotriazoles can be used as a stable isocyanate alternative, as has been demonstrated by its reaction with amines to synthesize

The aminolysis of aryl N-ethyl thiocarbamates (EtNHC(O)SC6H4Z) with benzylamines (XC6H4CN2NH2) in acetonitrile at 30.0 °C is investigated. The rates are faster than the corresponding values for aryl N-phenyl thiocarbamates (PhNHC(O)SC6H4Z), reflecting a stronger push to expel the leaving group by EtNH than the PhNH nonleavinggroup in a concerted process. The negative ρXZ (−0.86) and failure of the
在30.0°C下研究了芳基N-乙基硫代氨基甲酸酯(EtNHC(O)SC 6 H 4 Z)与苄胺(XC 6 H 4 CN 2 NH 2)的氨解作用。该速率比芳基N-苯基硫代氨基甲酸酯(PhNHC(O)SC 6 H 4 Z)的相应值快,反映出在协同过程中,EtNH推动离去基团的能力比PhNH非离去基团强。负ρXZ(-0.86)和发现的反应性-选择性原则的失败与一致的机制是一致的。涉及氘化的亲核试剂动力学同位素效应(ķ ħ / ķ d = 1.5-1.7)和低Δ ħ ⧧与大的负Δ小号⧧数值表明氢键环状过渡状态。
