1,3‐Dipolar Cycloaddition of Azomethine Ylides to Aldehydes: Synthesis of anti α‐Amino‐β‐Hydroxy Esters
A 1,3-dipolar cycloaddition reaction of azomethine ylides to aldehydes is described. The azomethine ylides, generated by thermal electrocyclic ring opening of aziridines, adds to aldehydes in good ...
