[reaction: see text] A simple and efficient one-pot, three-component synthesis of highly functionalized pyrrolidines via cascade imine --> azomethine ylide --> 1,3-dipolar cycloadditions is reported. Admixing a variety of aldehydes,
dimethyl 2-aminomalonate
, and electron deficient alkenes in
THF
leads to the clean production of pyrrolidines in good to excellent yields. The mild reaction conditions enabled the generation of previously inaccessible azomethine ylides from enolizable aldehydes. Endo selectivity was exclusive with N-phenyl maleimide and maleic anhydride. Good chemo-, regio-, and stereoselectivities were observed with methyl acrylate, though catalysis by Ag(I) was necessary with this dipolarophile.
