J.; Bertrand, Sophie M.; Bower, John F. published the artcile< Modular Access to Eight-Membered N-Heterocycles by Directed Carbonylative C-C Bond Activation of Aminocyclopropanes>, Recommanded Product: 5-Fluoroindole-2-carboxylic acid, the main research area is aminocyclopropane rhodium regioselective diastereoselective carbonylative heterocyclization; azocane preparation; C−C activation; azocanes; cyclopropanes; rhodium.
Aminocyclopropanes equipped with pendant nucleophiles undergo carbonylative heterocyclization triggered by C-C bond activation to generate eight-membered N-heterocycles, e.g., I. In these processes, intramol. “”capture”” of a rhodacyclopentanone intermediate by an aryl or N-based nucleophile is followed by C-C or C-N bond-forming “”collapse”” to the targets. These studies demonstrate how the combination of cyclopropane strain release and the templating effect of catalytically generated metallacycles can be harnessed to enable otherwise challenging medium ring closures.
Angewandte Chemie, International Edition published new progress about C-C bond activation. 399-76-8 belongs to class indole-building-block, and the molecular formula is C9H6FNO2, Recommanded Product: 5-Fluoroindole-2-carboxylic acid.
