Abstract We report here the reactivity of 6α,7α-epoxyhimachal-2-ene with dibromocarbene generated in situ by phase-transfer catalysis. The stereochemistry of products resulting from dibromocyclopropanation has been established by X-ray crystallography. Compound 3 is orthorhombic P212121 with a = 7.549 (1), b = 8.432 (1), c = 24.469 (1) Å, V = 1559.8 (5) Å3, Z = 4 and compound 5 is monoclinic P21 with a = 8.779 (1), b = 15.684 (1), c = 12.111 (1) Å, β = 91.869 (1)°, V = 1666.7 (4) Å3 and Z = 4.
