Facile One-Pot Synthesis of N-acyl-1H-1,2,3-benzotriazoles from Internal and Terminal Olefinic Fatty Acids and Their Antimicrobial Screening

抄録

N-acyl-1H-1,2,3-benzotriazoles were prepared in good yields by the reaction of benzotriazole and thionyl chloride with olefinic fatty acids under mild reaction conditions. The new compounds 1-(undec-10-enoyl)-1H-1,2,3-benzotriazole (5a),1-[(Z)-octadec-9-enoyl]-1H-1,2,3-benzotriazole (5b), 1-[(9Z,12R)-12-hydroxyoctadec-9-enoyl]-1H-1,2,3-benzotriazole (5c), 1-[(9R,12Z)-9-hydroxyoctadec-12-enoyl]-1H-1,2,3-benzotriazole (5d) formed were characterized on the basis of elemental analysis and spectral data. All the newly synthesized compounds (5a-5d) were screened for their antimicrobial activity and showed good antifungal activity.
