synthesis of pyrrolidines starting from phosphonium ylides, N-alkylglycines and carbonyl compounds was performed in 37–87% yields. This approach is based on a Wittig/Huisgen tandem reaction and simultaneous generation of the two reactive intermediates: alkene and azomethine ylide from the same carbonyl compound. Both stabilized and nonstabilized azomethine ylides were employed in this process allowing the construction
