ChemInform Abstract: 1,3-Dipolar Cycloaddition Reactions of 2-Phenyl-4-arylideneoxazol-5(4H)-ones with Nitrile Imines. A Reinvestigation of the Regiochemistry of the 1,3-Dipolar Cycloaddition Reactions of 2-Phenyl-4-arylideneoxazol-5(4H)-ones with Nitrile Oxides.
Abstract
By this reaction some compounds such as (III) and (VII) are isolated regioselectively.
ChemInform Abstract
By this reaction some compounds such as (III) and (VII) are isolated regioselectively. These products can serve as a source of pyrazoline amino acid derivatives such as (V). In the light of the results, the regiochemistry of the reaction with nitrile oxides is reexamined and the same regiochemistry is observed.
