• Catalytic 1,4-Rhodium(III) Migration Enables 1,3-Enynes to Function as One-Carbon Oxidative Annulation Partners in CH Functionalizations
  作者：David J. Burns、Hon Wai Lam

  日期：2014.9.8

  1,3‐Enynes containing allylic hydrogens cis to the alkyne are shown to act as one‐carbon partners, rather than two‐carbon partners, in various rhodium‐catalyzed oxidative annulations. The mechanism of these unexpected transformations is proposed to occur through double CH activation, involving a hitherto rare example of the 1,4‐migration of a RhIII species. This phenomenon is general across a variety

  Ru(de) awakening: The synthesis of carbocycles by the ruthenium‐catalyzed oxidative annulation of alkynes with 2‐aryl cyclic 1,3‐dicarbonyl substrates is described. Proceeding by the functionalization of CH and CH bonds, and the formation of an all‐carbon quaternary center, the reaction provides a diverse range of spiroindenes in good yields with high levels of regioselectivity.
