WebSep 5, 2005 · The best enantioselectivity was noted for t-butyl glyoxylate 7c, a slightly lower one for the isopropyl derivative 7b and a comparable one for n-butyl glyoxylate 7a (cf. entries 3, 6 and 9). In all the investigated reactions, the use of complex ( R , R )- 6 resulted in formation of the predominating enantiomers 8a – c with a (2 R ) configuration.
