Abstract

A series of protected L‐norvaline homo‐oligomers from dimer to heptamer was prepared by the dicyclohexylcarbodiimide and acid azide coupling methods. In the course of our synthetic approach t‐butyloxycarbonyl as the N‐protecting and methyl ester as the C‐protecting end groups were used. The oligomers prepared in this manner were characterized and found to be chemically and optically pure. In the accompanying paper an analysis of the conformational preferences in solution of these low molecular weight protected homo‐L‐norvalines in comparison with isomeric L‐valines will be reported.

New chiral porphyrins were obtained in reasonable yields in three steps, starting from the αβαβ atropisomer of mesotetrakis(o-aminophenyl)porphyrin (TAPP). These potential catalysts for the enantioselective epoxidation of alkenes were obtained by the reaction of different linkers on the same L- prol
