The title compound, C(20)H(33)ClN(2)O(3), was obtained via a tandem asymmetric Michael addition-elimination reaction of 3,4-dichloro-5-(S)-(l-menth-yloxy)furan-2(5H)-one and 1-ethyl-piperazine in the presence of potassium fluoride. The mol-ecular structure contains an approximately planar five-membered furan-one ring [maximum atomic deviation = 0.024 (2) Å] and two six-membered rings adopting chair conformations. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure. ...[more]
