An efficient, simple and catalyst-free synthesis of spiro[indeno[1,2-b]pyrazolo[4,3-e]pyridine indoline]diones and spiro[acenaphthylene-indeno[1,2-b]pyrazolo[4,3-e]pyridine]diones by the three-component reaction of 1,3-indandione, pyrazol-5-amines and isatins or acenaphthylene-1,2-dione in refluxing ethanol is reported. Reaction of 2,6-diaminopyrimidin-4(3H)-one with 1,3-indandione and isatins resulted
A radical cyclization of N‐methyl‐N‐arylpropiolamide to isatins via an oxidative cleavage of a carbon‐carbon triple bond has been developed. In the presence of oxone and NaNO2, a variety of N‐methyl‐N‐arylpropiolamides were smoothly transformed into isatins. A nitration reaction proceeded along with the oxidative cyclization; both nitrated and non‐nitrated isatins were obtained in a one‐pot reaction
l-Proline was found to be a versatile organocatalyst for the synthesis of new spirooxindole derivatives in good yields under mild reaction conditions using 1-propanol as a solvent.
