made conveniently through condensation of corresponding isatins with N-diphenylmethyl amine, are deprotonated to form azaallyl anions. Allylation and alkylation of this type of intermediates proceed smoothly with diverse C-electrophiles. Acidic work up finishes 3-amino-3-allyl/alkyl oxindoles. The overall transformation equals to an umpolung process at the C3 of isatins.

design, synthesis, biologicalevaluation, SAR and potential binding mode of indoline-like LRRK2 inhibitors and their preliminary neurogenic effect in neural precursor cells isolated from adult mice ventricular-subventricular zone. These results open new therapeutic horizons for the use of LRRK2 inhibitors as neuroregenerative agents. Moreover, the indolinone derivatives here prepared, inhibitors of the

The paper describes the synthesis and antileishmanial activity of N-substituted imines, obtained from the reactions of primary amines with three biologically important aldehydes/ketones, thiophene-2-carbaldehyde, 2- hydroxybenzaldehyde (salicylaldehyde) and indoline-2,3-dione. Of the fourteen compounds screened from three classes, five compounds showed significant antileishmanial activity. Among the three classes of imines, the class of N-(2- thienylidene)amines showed much better activity than the other two classes. N-(2-Thienylidene)benzhydrylamine showed IC50 value of 0.51 μg/ml. The effect of substituents on the bioactivity is discussed.
A family of chiral quaternary 3-aminooxindole butenolides has been synthesized by BINOL-derived phosphoric acid-catalyzed addition of trimethylsiloxyfuran to isatin-derived ketimines. Such a vinylogous Mannich-type reaction was found to produce diastereoisomeric butenolides in good yields and in most cases high enantiomeric excesses. The configurational assignment of the obtained products was safely
