We present the crystal and molecular structures of two new N-phthalyl-3-amino-2-arylpropionic acid pantolactonyl ester derivatives with 4-fluorophenyl and 3,4-dimethoxyphenyl as the aryl group, 2,3,4,5-tetrahydro-4,4-dimethyl-2-oxofuran-3-yl 3-phthalimido-2-(4-fluorophenyl)propanoate, C23H20FNO6, and 2,3,4,5-tetrahydro-4,4-dimethyl-2-oxofuran-3-yl 3-phthalimido-2-(3,4-dimethoxyphenyl)propanoate ethyl acetate hemisolvate, C25H25NO8·0.5C4H8O2. This structural study confirms the S configuration of the C2 and validates the stereospecificity of our synthesis strategy.
