The title compound, C(17)H(26)ClNO(5), was prepared via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)--one and l-alanine in the presence of potassium hydroxide. The five-membered furan-one ring is approximately planar while the six-membered menth-yloxy ring adopts a chair conformation. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.
标题化合物C(17)H(26)ClNO(5)是通过(5S)-3,4-二氯-5-(L-薄荷氧基)呋喃-2(5H)-酮与L-丙氨酸在氢氧化钾存在下进行串联不对称迈克尔加成-消除反应制备的。五元呋喃酮环近似平面，而六元薄荷氧基环呈椅式构象。晶体堆积通过分子间的O-H⋯O和N-H⋯O氢键得以稳定。
