چکیده
The title compound, C(34)H(54)Br(2)N(2)O(6), was obtained by the Michael addition-elimination reaction of (5S)-5-(l-menthyl-oxy)-3,4-dibromo-furan-2(5H)-one with 1,6-hexa-nediamine in the presence of triethyl-amine. The crystal structure contains two chiral five-membered furan-one rings, in twist and envelope conformations, and two six-membered cyclo-hexane rings in chair conformations.
