Ase. Karlstrom et al., Ferrocenyl thiolates as ligands in the enantioselective copper-catalyzed substitution of allylic acetates with Grignard reagents, SYNLETT, 2001, pp. 923-926
The application of ferrocenyl thiolates as ligands in copper-catalyzed asym
metric substitution reactions of allylic acetates with Grignard reagents is
reported. The catalyst formed from lithium thiolate 12 gave the gamma -pro
ducts in high selectivity and with up to 64% ee.
