, p. 2014 - 2018 (1992)
1,3-Dipolar cycloadditions of the C-aryl-N-alkylnitrones 2a-c and the C,N-dialkylnitrones 2e-g with the (E)-1-alkyl-2-nitroethenes 1a,b afforded predominantly or exclusively the cis-3-substituted 4-nitroisoxazolidines 3a-d and 3f-h. Exceptions are the rea
Enantioselective nitrone cycloadditions of α,β-unsaturated 2-acyl imidazoles catalyzed by bis(oxazolinyl)pyridine-cerium(IV) triflate complexes

Enantioselective nitrone cycloadditions with β-substituted α,β-unsaturated 2-acyl imidazoles catalyzed by bis(oxazolinyl) pyridine-cerium(IV) triflate complexes 1 have been reported. The isoxazolidine products were efficiently transformed into densely functionalized β′-hydroxy-β-amino acid derivatives.

Reaction of isoxazolidines with carbon monoxide in benzene, catalyzed by the dimer of chloro(1,5-cyclooctadiene)rhosium, results in the formation of tetrahydro-1,3-oxazin-2-ones as the major or only product, often in fine yields.A novel conversion of 3-ar
