and isatylidene malononitriles in dry acetonitrile at room temperature afforded polysubstituted spiro[indoline-3,4′-pyridines] in good yields and with high diastereoselectivity. Under similar reaction conditions, the corresponding functionalized spiro[indene-2,4′-pyridines] were also obtained from the three-component reactions containing 2-(1,3-dioxo-1H-inden-2(3H)-ylidene)malononitrile.

derivatives were facilely synthesized via 1,3-dipolar cycloaddition of azomethine ylide generated from sarcosine and paraformaldehyde with various 3-methyleneoxindolines. The relative configuration of obtained spiro[indoline-3,3′-pyrrolidines] was successfully elucidated by determination of nine single-crystal structures. The antimicrobialactivities and the inhibitory activity towards acetylcholinesterase
