The present invention features formulations of indolinones which compounds are ionizable as free acids or free bases. The formulation is suitable for parenteral or oral administration, wherein the formulation comprises an ionizable substituted indolinone, and a pharmaceutically acceptable carrier therefor. The term “ionizable substituted indolinone” includes pyrrole substituted 2-indolinones which, in addition to being otherwise optionally substituted on both the pyrrole and 2-indolinone portions of the compound, are necessarily substituted on the pyrrole moiety with one or more hydrocarbon chains which themselves are substituted with at least one polar group. The formulations and the compounds themselves are useful for the treatment of protein kinase related disorders as discussed herein.

A unified catalyticasymmetric (N+1) (N=4, 5) annulation reaction of oxindoles with bifunctional peroxides has been achieved in the presence of a chiral phase-transfer catalyst (PTC). This general strategy utilizes peroxides as unique bielectrophilic four- or five-atom synthons to participate in the C−C and the subsequent umpolung C−O bond-forming reactions with one-carbon unit nucleophiles, thus providing
在手性相转移催化剂 (PTC) 的存在下,已经实现了羟吲哚与双官能过氧化物的统一催化不对称 ( N +1) ( N =4, 5) 环化反应。这种通用策略利用过氧化物作为独特的双亲电四原子或五原子合成子参与 C−C 和随后与单碳单元亲核试剂的 umpolung C−O 键形成反应,从而提供了一种独特的方法来获得有价值的手性螺吲哚-四氢呋喃和-四氢吡喃在温和条件下具有良好的产率和高对映选择性。进行 DFT 计算以合理化高对映选择性的起源。还证明了所得产物的克级合成和合成效用。
