  Divergent base-induced reactivity of cycloalkenyl-1-diazenes

  摘要：

  The different base-promoted regioselectivities of the ring closure processes in the reactions between cycloalkenyl-1-diazenes and beta-ketoesters are investigated. Under the appropriate conditions it is possible to turn the synthesis towards cycloalkenyliden-pyrroles or functionalized 3-hydroxy-hydrocinnolines. The aromatization procedure of the heteroring counterpart of the 3-hydroxy-hydrocinnolines is also reported. (C) 2010 Elsevier Ltd. All rights reserved.
