A rhodium-catalyzedannulation between aroyl sulfoxonium ylides and anthranils has been developed to synthesize 10H-indolo[1,2-a]indol-10-one derivatives. This reaction started with an unpredented (4 + 1) annulation toward N-(2-formylphenyl) indolones, proceeding with the sequential ortho-amination of the C-H bond in aroyl sulfoxonium ylides by anthranils and the insertion of N-H to carbene. Finally

The synthesis and pharmacology of a new series of 3-piperazinylmethyl-3a,4-dihydro-3H-[1]benzopyrano[4,3-c]isoxazoles that combine central serotonin (5-HT) reuptakeinhibition with alpha(2)-adrenoceptor blocking activity is described as potentialantidepressants. Four compounds were selected for further evaluation, and the combination of both activities was found to be stereoselective, residing mainly
