Abstract

The axially chiral bis(alpha-amino acid)s cis-2 and trans-2 as possible building blocks for polymeric structures of novel type of helicity were prepared. Their configuration has been determined by NMR spectroscopy and, in the case of the trans-isomer, confirmed by single-crystalX-ray diffraction. Analogous pair of stereoisomeric diacids cis-3 andtrans-3, devoid of the amino groups, was also prepared and their configuration assigned. The observed differences in the NMR spectra of cis-and irans-isomers of 2 and 3 are discussed from the viewpoint of their different symmetry properties.
