β¦ Synopsis
One-pot synthesis of novel ferrocene grafted N-methyl-spiropyrrolidines has been accomplished in good yields through a facile 1,3-dipolar cycloaddition reaction of various azomethine ylide derived from ninhydrin and sarcosine with various ferrocene derivatives as dipolarophile. The regiochemical and stereochemical outcome of the cycloaddition reaction is ascertained by X-ray crystallographic studies of one of the cycloadducts.

A simple and efficient method for the synthesis of novel spiropyrrolidines has been accomplished by regioselective 1,3-dipolar cycloaddition reactions of an azomethine ylide generated by thermalring opening of cis-1-cyclohexyl-2-phenyl-3-benzoyl aziridine with various (E)-3-arylidene-4-chromanones.
## Abstract The 1,3βdipolar cycloaddition of unstabilized __N__βmethyl azomethine ylide to mononitro benzazoles was studied. Depending on the nature of substituents and annelated azoles, the reaction affords previously unknown isoindole fused heterocyclic systems. The reactivity of the cycloadducts
