, p. 1613 - 1616 (1989)
New, more efficient enantiomerically pure (camphorylsulfonyl)oxaziridines are prepared by mono alkylation of the dianion of (camphorylsulfonyl)imine at the carbon atom adjacent to the sulfonyl group.

Paragraph 0105; 0106, (2013/06/27)
The present invention provides efficient and economical methods for synthesis of (-)-2-exo-morpholinoisoborne-10-thiol, its enantiomer, and related chiral catalysts. Novel compounds and methods of asymmetric synthesis are also disclosed.
Synthesis of camphorsulfonamide-based quinoline ligands and their N-oxides: first use in the enantioselective addition of organozinc reagents to aldehydes
Martinez, Ricardo,Zoli, Luca,Cozzi, Pier Giorgio,Ramon, Diego J.,Yus, Miguel
experimental part, p. 2600 - 2607 (2009/04/11)
The preparation of several camphorsulfonamide-based quinoline derivatives and their N-oxides was accomplished via an indirect Friedlaender synthesis using aminobenzylic alcohols and RuCl2(DMSO)4 as a catalyst. These ligands were tested in the enantioselective addition of dialkylzinc reagents to aldehydes, with enantiomeric excesses up to 96%. A similar protocol using triphenylborane and diethylzinc gave the corresponding phenylation process.
