Abstract

The title compound, C(20)H(32)ClNO(3), was obtained via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)-one and 4-methyl-piperidine in the presence of potassium fluoride. The furan-one ring is approximately planar [maximum atomic deviation = 0.022 (2) Å] while the cyclo-hexane ring adopts a chair conformation. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
