Abstract
In previous studies"2 we synthesized (+)-2-t-butyl-2methyl-l,3-benzodioxole-4-carboxylic acid [(+)-TBMB carboxylic acid] as a chiral derivatizing agent for amines and alcohols. In the present study an X-ray analysis was performed on its L-phenylalanine methyl ester derivative, N{(+)-TBMB carbonyl-L-phenylalanine methyl ester], in order to determine the absolute configuration of (+)-TBMB carboxylic acid. A transparent colorless prism (ca. 0.2X0.3X0.3 mm) was obtained from hexane and was used for an X-ray study. All hydrogen atoms (26H), except for NH, were
