title: (5S)-3-Chloro-4-diallyl-amino-5-[(1R,2S,5R)-2-isopropyl-5-methyl-cyclo-hex-yloxy]furan-2(5H)-one.
abstract: The title compound, C(20)H(30)ClNO(3), was obtained via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)-2(5H)-furan-one and diallyl-amine in the presence of potassium fluoride. The mol-ecular structure contains an approximately planar five-membered furan-one ring [maximum atomic deviation = 0.0221 (3) Å] and a six-membered ring adopting a chair conformation.
