  Tandem transformations of tetrahydrobenzothieno[2,3-c]pyridines in the presence of activated alkynes

  摘要：

  The reactivity of some new tetrahydrothienopyridines towards activated alkynes was investigated. A novel cascade cleavage-spiroannulation process, leading to the formation of previously unreported derivatives of 1'H-spiro[1-benzothiophene-3,4'-pyridine] was discovered and studied.
