The synthesis of orthogonally protected β-amino acid 3-tert-butoxycarbonylamino-1,2,3,4-tetrahydro-2-naphthoic acid benzyl ester (Boc-βAtc-OBn) is described. The route to these constrained phenylalanineanalogs features a SmI2-mediated aziridine cleavage resulting in a β-amino ester. The stereochemistries have been determined by X-ray crystallographic analyses.
