title: N-[(2S)-4-Chloro-2-(l-menthyloxy)-5-oxo-2,5-dihydro-3-furyl]-l-alanine.
abstract: 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.
