Synthesis of Proline Derivatives by 1,3-Dipolar Cycloaddition of Azomethine Ylide Generated from an Organosilicon Compound
The 1,3-dipolar cycloaddition of azomethine ylides generated from methyl N-(trimethylsilylmethyl)iminoacetate and benzyl bromide or a catalytic amount of trifluoroacetic acid has been found to give the corresponding proline derivatives.

A NEW SYNTHETIC METHOD FOR PROLINE DERIVATIVES VIA THE AZOMETHINE YLIDE INTERMEDIATE GENERATED FROM METHYL N-(TRIMETHYLSILYLMETHYL)IMINOACETATE
Proline derivatives were found to be synthesized by the 1,3-dipolar cycloaddition of the azomethine ylide, produced from methyl N-(trimethylsilylmethyl)iminoacetate and benzyl bromide or a catalytic amount of trifluoroacetic acid, to conjugated olefins.
