Diastero- and enantioselective intramolecular carbometalation reaction
摘要:
The zinc-catalyzed addition of various alkynes to acylsilanes followed by a Zn-Brook rearrangement and either the Zn-ene-allene or Zn-yne-allene cyclization led to the enantio- and diastereoselective formation of carbocycles in a single-pot operation. (C) 2010 Elsevier Ltd. All rights reserved.
