  tert‐Butyl Nitrite Promoted Visible‐Light‐Induced Steric‐Hindrance‐Regulated Concurrent Cross‐Coupling and Regioselective Nitration of 3‐Alkylidene‐2‐oxindoles

  摘要：

  A tert‐butyl nitrite (TBN) promoted visible‐light‐induced one‐pot C−N cross coupling reaction of 3‐alkylidene‐2‐oxindoles with benzene‐1,2‐diamine was explored. Simultaneously, the indoline motif of 3‐alkylidene‐2‐oxindoles as well as 3‐ylidene oxindoles are regioselectively nitrated at the C‐6 position by in‐situ formed NO2 radical. (E)‐3‐(2‐(aryl)‐2‐oxoethylidene)oxindole and (E)‐3‐ylidene oxindole produce distinct nitrated diastereomeric coupling products, a phenomenon influenced by the steric bulk of the functional group. The experimental findings suggest the potential involvement of a radical pathway in this reaction.

  isothiourea HyperBTM catalyzes the acylative kinetic resolution of a wide range of tertiary heterocyclic alcohols under mild conditions with high selectivity. The synthetic utility of the methodology has been demonstrated with the preparation of two bioactive targets. Kinetic analysis reveals a fractional reaction order with respect to the alcohol concentration.

  A series of 3‐hydroxy‐3‐phenacyloxindole analogues of isatin were designed, synthesized, and evaluated in vitro for their inhibitory activity toward monoamine oxidase (MAO) A and B. Most of the synthesized compounds proved to be potent and selective inhibitors of MAO‐A rather than MAO‐B. 1‐Benzyl‐3‐hydroxy‐3‐(4′‐hydroxyphenacyl)oxindole (compound 18) showed the highest MAO‐A inhibitory activity (IC50:

  Oxidation of tertiary alcohol of the type 3-hydroxy-3-phenacyloxindoles using the combination of phenyliodine diacetate and molecular iodine in methanol results in oxidative cleavage of C2-C3 bond to form isocyanate as an intermediate with its subsequent trapping by methanol to form ortho-carbamates of 1,3-diaryl carbonyl compounds which further undergoes concurrent cyclization to furnish 2-hydroxy-2-aryl/alkyl-2
