A series of cycZo(Aaminoacyl-L-Ala) (fl) (A=a,@dehydro) were prepared from cycZo(Gly-L-Ala) and corresponding aldehyde, and hydrogenated with Pd black in MeOH. Chiral inductions producing CycZo(L-aminoacyl-L-Ala) (2) from 2 were 96-99% in the case of L-Aba (2-eminobutanoic acid), L-Val, L-Leu, and L

The calix [4]arene framework was readily modified to generate a number of chiral BINOL-based diphosphite ligands (3) capable of forming in situ Rh-complexes which catalyzed the asymmetric hydrogenation of model substrates methyl-(Z)-2-(acetamido)acrylate (1a) and methyl-(Z)-2-(acetamido)cinnamate (1
