Synthesis of Oxindole Derivatives via Intramolecular C–H Insertion of Diazoamides Using Ru(II)-Pheox Catalyst

This work presented the efficient intramolecular aromatic C–H insertion of diazoacetamide. The 1a–1o diazo compounds (except for 1k) were converted into their corresponding oxindoles via an intramolecular C–H insertion reaction in the presence of a Ru catalyst. The Ru-Pheox catalyst was shown to be highly efficient in this transformation in terms of the regioselectivity, producing the desired products in excellent yield (99%). The efficiency of the Ru catalyst reached 580 (TON) and 156 min?1 (TOF).

Method for preparing Nintedanib,I intermediate through one-pot method

The invention relates to a method for preparing Nintedanib,I key intermediate N-(4-aminophenyl)-N-methyl-2-(4-methyl piperazine-1-group)acetamide through a one-pot method. The method comprises the steps that according to the technical scheme, N-methyl-4-nitroaniline is dissolved in an aqueous solution of an organic solvent and alkali, mixing is carried out, then chloroacetyl chloride or bromoacetyl bromide is dropwise added, and a first-stage reaction is carried out for 0.1-3 hours at the temperature of 0-70 DEG C; a water layer is removed, N-methyl piperazine is added, a second-stage reactionis carried out, and reacting is carried out for 2-10 hours at the temperature of 0-75 DEG C; then a reducing reagent is added, a third-stage reaction is carried out for 8-36 hours at the temperatureof 0-75 DEG C and the pressure of 15-100 psi. After the reaction is finished, filtering is carried out to remove the reducing reagent, the reaction liquid is condensed, a reverse phase solvent is added, crystallization is carried out, and the Nintedanib,I key intermediate N-(4-aminophenyl)-N-methyl-2-(4-methyl piperazine-1-group)acetamide (formula B) is obtained. According to the preparation method, the raw materials are easy to obtain, the process is simple, and the method is economical, environmentally friendly and suitable for industrial production.

A Direct C-H/Ar-H Coupling Approach to Oxindoles, Thio-oxindoles, 3,4-Dihydro-1 H-quinolin-2-ones, and 1,2,3,4-Tetrahydroquinolines

A copper(II)-catalysed approach to oxindoles, thio-oxindoles, 3,4-dihydro-1H-quinolin-2-ones, and 1,2,3,4-tetrahydroquinolines via formal C-H, Ar-H coupling is described. In a new variant, copper(II) 2-ethylhexanoate has been identified as an inexpensive and efficient catalyst for this transformation, which utilises atmospheric oxygen as the re-oxidant. Copper(II) 2-ethylhexanoate: The synthesis of oxindoles, thio-oxindoles, 3,4-dihydro-1H-quinolin-2-ones, and 1,2,3,4-tetrahydroquinolines from linear precursors by direct C-H, Ar-H coupling by using a single copper catalyst is reported (see scheme; DIPEA=diisopropylethylamine, EWG=electron-withdrawing group).
