Synthesis of new chiral heterocycles of the pyrazole and 2-isoxazoline types from (+)-3-carene.
摘要:
Preparation of chiral heterocyclic compounds of the pyrazole and 2-isoxazoline types starting from natural monoterpene hydrocarbon (+)-3-carene is described. Stereochemical assignment of the compounds synthesized is made by NMR spectroscopy and X-ray analysis together with the data obtained by molecular mechanics and quantum chemical calculations.
