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 14. BRONSTED AND LEWIS ACID CATALYSIS OF CYCLOADDITIONS OF ARYLIDENE IMINES OF α-AMINO ACID ESTERS

, p. 5887 - 5898 (2007/10/02)
Cycloadditions of arylidene imines of α-amino acid esters to a range of dipolarophiles show substantial rate enhancements in the presence of Bronsted and Lewis acids.For Bronsted acids the rate is related to the pKa of the acid and cycloadditio
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
