Enantioselective Intramolecular CH-Insertions upon Cu- Catalyzed Decomposition of Phenyliodonium Ylides
Published: 11 September 2000 by MDPI in The 4th International Electronic Conference on Synthetic Organic Chemistry session General Organic Synthesis
Abstract: The Cu-catalyzed intramolecular CH insertion of phenyliodonium ylide 5b has been investigated at 0 °C in the presence of several chiral ligands. Enantioselectivities vary in the range of 38–72 %, and are higherthan those resulting from reaction of the diazo compound 5c at 65 °C. The results are consistent with a carbenoid mechanism for Cu-catalyzed decomposition of phenyliodonium ylides.
