The regio-and stereoselectivity of the c cloadditioa between C.N-diphenylnitrone and 2-endo-acetoxy-7-oxabicyclo 2.2.l]hept-S-enee 2-exo-carbonitrile has been studied. Subsequent fragmentation of the isoxazolidine ring with mCPBA followed by acidic hydrolysis yields highly functionalized oxanorborne
Second-order rate constants and activation parameters of 1,3-dipolar cycloaddition reaction between C,N-diphenylnitrone and dimethyl fumarate were obtained in various solvents and aqueous solutions at 65ЊC. Second-order rate constants of the reaction in water and ethylene glycol are approximately 33
