mmol/L and 0.00942 mmol/L, respectively) compared with CPT (LC50 0.19719 mmol/L) against T. Cinnabarinus. Based on the observed bioactivities, preliminary structure–activityrelationship (SAR) correlations were also discussed. Furthermore, a three-dimensional quantitativestructure–activityrelationship (3D-QSAR) model using comparative molecular field analysis (CoMFA) was built. The model gave statistically

radical carbamoylation/cyclization reaction of N‐arylacrylamides with hydrazinecarboxamides has been developed for facile access to 2‐(oxindol‐3‐yl)acetamides, which had been utilized as precursors in the synthesis of natural bioactive pyrrolidinoindolines. In the presence of 1 mol% of copper(II) carbonate and 4 equiv. of tert‐butyl hydroperoxide, a wide range of N‐arylacrylamides underwent highly regioselective

appropriate isocyanate and isothiocyanate respectively, or alternatively by condensing the appropriate diketone with the proper substituted semicarbazide or thiosemicarbazide. The structures of the prepared compounds were fully determined by analytical and spectral methods. Preliminary biological screening of the prepared compounds revealed significant antibacterial and cytotoxic activities for some compounds
An efficient method for the carbamoylation of quinoline N‐oxidescatalyzed by copper was developed. A variety of quinoline N‐oxides and hydrazinecarboxamides with different groups was well tolerated in this system.
