摘要

Abstract The title compound and the corresponding anion have been conveniently used as precursors of substituted divinylketones in both carbo-and heterocyclization reactions in one- pot, three-step sequences leading to a wide variety of substituted carbo-and heterocyclic ring systems, as well as to multifunctionalized linear carbon frameworks. The compounds generated through the use of this multi-coupling reagent represent useful synthons for the ...
