Photochemical asymmetric synthesis of phenyl-bearing quaternary chiral carbons using chiral-memory effect on beta-hydrogen abstraction by thiocarbonyl group.
Quaternary chiral carbons were effectively generated from tertiary chiral carbons via photochemical intramolecular beta-hydrogen abstraction reaction of thioimides involving the highly-controlled chiral-memory effect.
