Crystal structure of 2-isopropyl-5,7′-dimethyl-1′,3′,3a',6′,8a',8b'-hexahydrospiro[cyclohexane-1,6′-furo[3,4-d]imidazo[1,5-b]isoxazol]-8′(7′H)-one

Abstract

Cyclo­addition reaction between a menthone-based chiral nitrone and 2,5-di­hydro­furan under microwave activation affords a enanti­opure cyclo­adduct in good yields and with high stereoselectivity
