The process involving a rearrangement of pyrrolidino[3,4- c ]pyrrolidine to another pyrrolidino[3,4- b ]pyrrolidine using sodium methoxide as base is fully studied. The effects of the substituents are analyzed during the ring-opening/ring-closing sequence
X=Y-ZH Systems as Potential 1,3-Dipoles. Part 8. Pyrrolidines and Δ5-Pyrrolines (3,7-Diazabicyclooctenes) from the Reaction of Imines of α-Amino Acids and their Esters with Cyclic Dipolarophiles. Mechanism of Racemisation of α-Amino Acid

Imines of α-amino acid esters with aromatic, heterocyclic, and aliphatic aldehydes generate azomethine ylides stereospecifically by a prototropic shift on heating in toluene.The azomethine ylides undergo cycloaddition to N-phenylmaleimide, maleic anhydrid
