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.

ABSTRACT Spirooxindoles are a class of molecules possessing significant biological effects such as antiviral, antifungal, antibacterial and anticancer properties. Herein we report a series of spirooxindole molecules having 2-amino pyran-3-carbonitrile and with two ester groups. These molecules were prepared by the reaction of dialkyl acetone-1,3-dicarboxylate and isatilidenes in the presence of triethyl

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
Abstract Herein, an efficient and sustainable one-pot, four-component access to rhodanine-oxindole derivatives is achieved by a reaction between primary amines, carbon disulfide, ethyl chloroacetate, and cyano-substituted alkenyl oxindoles. The reaction was conducted without any harsh conditions as well as exhausting workup in polyethylene glycol (PEG) as a green solvent at room temperature and delivered
