indolones were synthesized as diastereomeric mixtures applying a novelconsecutivethree-component Heck-condensation sequence in the sense of a one-pot synthesis. The N-substitution pattern was found to be crucial for the fluorescence in the solid state. Accordingly, the synthetic route was extended to a consecutive four-component reaction to generate a diverse compound library of Boc-substituted 3-arylallylidene

A series of 3-(benzylidine)indolin-2-one derivatives were synthesized and evaluated for their in vitro binding to alpha synuclein (alpha-syn), beta amyloid (A beta), and tau fibrils. Compounds with a single double bond in the 3-position had only a modest affinity for alpha-syn and no selectivity for alpha-syn versus A beta or tau fibrils. Homologation to the corresponding diene analogues yielded a mixture of Z,E and E,E isomers; substitution of the indoline nitrogen with an N-benzyl group resulted in increased binding to alpha-syn and reasonable selectivity for alpha-syn versus and tau. Introduction of a para-nitro group into the benzene ring of the diene enabled separation of the Z,E and E,E isomers and led to the identification of the Z,E configuration as the more active regioisomer. The data described here provide key structural information in the design of probes which bind preferentially to alpha-syn versus A beta or tau fibrils.
