Abstract

The title compound, C(20)H(30)BrNO(3), was obtained via a tandem asymmetric Michael addition-elimination reaction of 3,4-dibromo-5-(S)-(l-menth-yloxy)-2(5H)-furan-one and diallyl-amine in the presence of potassium fluoride. In the mol-ecule, the five-membered furan-one ring is approximately planar [maximum atomic deviation = 0.030 (3) Å], and the six-membered cyclo-hexane ring adopts a chair conformation.
