✦ Synopsis

In the title compound, C 12 H 13 NO 4 , the phenyl and oxazolidine rings make a dihedral angle of 65.0 (1) . Weak C-HÁ Á ÁO hydrogen-bonding interactions lead to the formation of a chain parallel to the a axis.

## Abstract A 2‐oxo‐1,3‐oxazolidine‐4‐carboxylic acid was designed as a new, conformationally restricted building block for the construction of pseudopeptide foldamers. IR, ^1^H NMR and CD techniques, implemented by detailed DFT computational modeling, were exploited to investigate the preferred th
