3-Benzoyl-2-(4-methoxyphenyl)-4-phenyloxazolidine-5-carboxylic acid, (4S,5R)

The scaffold is heavily substituted with aromatic groups (benzoyl, phenyl, and p-methoxyphenyl), giving the molecule significant steric bulk and lipophilicity. This compound contains a five-membered oxazolidine ring bearing two contiguous stereocenters with defined (4S,5R) configuration, which is critical for downstream chiral fidelity.
