Sa. Popov et al., SYNTHESIS OF NEW CHIRAL HETEROCYCLES OF THE PYRAZOLE AND 2-ISOXAZOLINE TYPES FROM (-3-CARENE()), Tetrahedron : asymmetry, 5(3), 1994, pp. 479-489
Preparation of chiral heterocyclic compounds of the pyrazole and 2-iso
xazoline types starting from natural monoterpene hydrocarbon (+)-3-car
ene is described. Stereochemical assignment of the compounds synthesiz
ed is made by NMR spectroscopy and X-ray analysis together with the da
ta obtained by molecular mechanics and quantum chemical calculations.
