O. Miyata et al., AN EFFICIENT METHOD FOR REMOVAL OF CHIRAL AUXILIARIES, CAMPHORSULTAM AND 4-ISOPROPYL-2-OXAZOLIDINONE, Synlett, (8), 1994, pp. 637-638
An aluminum thiobenzyloxy ''ate'' complex is shown to be an efficient
reagent for removal of chiral auxiliaries such as camphorsultam and 4-
isopropyl-2-oxazolidinone.
