Abstract
The solid-phase catalytic hydrogenation of (R-4tert-butoxy-Δ1-pyrroline-2-carboxylic) acid under the action of hydrogen spillover was studied. The reaction proceeds stereoselectively with the predominant formation of thel-amino acid. The configuration of the asymmetric center formed is determined by that of the asymmetric C(4) atom. The major portion of the isotope label is incorporated into the allylic C(3) and C(5) positions, and the β-H atoms are more mobile. Using quantum-chemical calculations, the geometric structure of thel-hydroxyproline molecule was calculated, and the spin-spin coupling constants for this tritium-labeled amino acid were determined.
