Enantioselective iridium catalyzed internal redox allylation of phthalaldehyde 1a using substituted allylic acetates 2b–2j to form phthalides 3g–3o.a
|
Yields are of material isolated by silica gel chromatography. Enantioselectivities were determined by chiral stationary phase HPLC analysis. See Supporting Information for further experimental details.
