(Z)-2-Phenyl-4-arylidene-4,5-dihydro-oxazol-5-ones were synthesized by condensation of hippuric acid and aromatic aldehyde following the Erlenmeyer procedure, then reacted with aryldiazomethane in a highly diastereoselective 1,3-dipolar cycloaddition at room temperature to give spirocyclopropane derivatives in 86%~90% yields. The spirocyclopropane derivatives were readily converted into the corresponding trans- 2,3-diaryl-1-aminocyclopropanecarboxylic acid by treatment with absolute methanol containing catalytic amounts of sodium methoxide, then hydrolysis in 4 mol/L of HCl/HOAc. The structures and configurations were established on the basis of their elemental analyses and spectroscopic data, such as IR, 1H NMR, 13C NMR, MS and X-ray crystallography. The results indicated that 2,3-diaryl-1-aminocyclopropanecarboxylic acids with desired configurations could be synthesized with certain aromatic aldehyde and appropriate aryldiazomethane.

Key words: trans-2,3-diaryl substituted-1-aminocyclopropanecarboxylic acid, highly diastereoselective synthesis, 1,3-dipolar cycloaddition, X-ray crystallography
