Mannich bases obtained from cycloalkanones and methyl-ketones decompose on heating to give α,β-enones, which react in situ with nonstabilized azomethine ylides formed from spiro[anthracene-oxazolidines]. The final products, 3-acylpyrrolidines, were obtain

Three-component reactions of monoalkyl malonates, cyanoacetic acids or 2-ketocarboxylic acids, N-methylglycine, and formaldehyde were developed to rapidly access 3-substituted pyrrolidines in 17–97% yield. These reactions represent a double decarboxylative domino-sequence promoted by pyrrolidine and involve N-methylazomethine ylide as the reactive intermediate.
