α-Hydroxymethylaspartic acid: Synthesis and absolute configuration by X-ray analysis of its derivative (+)-4-benzoylamino-4-carboxy-γ-butyrolactone

(+)-4-Benzoylamino-4-carboxy-γ-butyrolactone was synthesized, and its structure solved by direct methods and refined to R = 0.033.The molecule adopts a skew conformation with a C7-N1-C8-C12 torsion angle of 59.6(2) deg.The lactone ring has an envelope con
