(NCEs) targeting multidrugresistant (MDR) bacterial infections, particularly those caused by Gram-negative pathogens. 4-Hydroxy-2-pyridones represent a novel class of nonfluoroquinolone inhibitors of bacterial typeIItopoisomerasesactiveagainst MDR Gram-negativebacteria. Herein, we report on the discovery and structure-activity relationships of a series of fused indolyl-containing 4-hydroxy-2-pyridones

A catalyst-free, three-component alkylation-condensation cascade for spiropyran synthesis has been developed, using readily available building blocks (indoles, alkyl halides, salicylaldehydes) and environmentally benign solvents (water, ethanol). A cascade approach enables this sequence to proceed under mild conditions which, in turn, promote broad substrate tolerance and operational simplicity. Consequently

intermolecular self-[3+3] and cross-[3+3] cycloaddition pathways. Multiple symmetric and nonsymmetric polycyclic hexahydrocarbazole scaffolds with hexacyclic 6/5/5/6/5/5/6 and pentacyclic 6/5/5/6/5/6 ring systems are synthesized with high efficiency and chemoselectivity using this strategy. Inspired by the unique radicaladdition pathway of cross-[3+3] cycloaddition, a highly controllable benzylic C–H functionalization
