1,3-Dipolar cycloaddition of diazoalkanes to (S)-(+)-3-[(4-methylphenyl) sulfinyl]-5,6-dihydropyran-2-one. Synthesis of optically pure cyclopropanes by denitrogenation of sulfinyl and sulfonyl pyrazolines

(Chemical Equation Presented) The addition of diazomethane and diazoethane to enantiopure (S)-(+)-3-[(4-methylphenyl)sulfinyl]-5,6-dihydropyran-2-one (3) afforded the corresponding pyrazolines 4 and 6-exo in good yields and with almost complete π-facial s
