โฆ Synopsis
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 oxanorbornenic hydroxyketones.
