Total Synthesis of Piericidin A1. Application of a Modified Negishi Carboalumination-Nickel-Catalyzed Cross-Coupling
摘要:
A total synthesis of the mitochondrial complex I inhibitor piericidin A1 is described. It features a unique strategy for the key disconnection, highlighting a modified Negishi carboalumination/Ni-catalyzed cross-coupling on a polyenyne precursor.
Carboalumination/Ni-catalyzed couplings. A short synthesis of verticipyrone
摘要:
Verticipyrone (1) has been synthesized in six overall steps from commercially available ethyl-2-methylacetoacetate. This represents the first successful application of a modified Negishi carboalumination nickel-catalyzed cross-coupling reaction to a chloromethylated pyrone. (C) 2009 Elsevier Ltd.
