Oxidative organocatalytic chemoselective: N -acylation of heterocycles with aromatic and conjugated aldehydes
Ta, Linda,Sundén, Henrik

Selective acylation of indoles is cumbersome often involving the need for sensitive and reactive acyl chloride derivatives or coupling reagents. Here we report a mild, functional group tolerant and highly chemoselective oxidative carbene catalyzed N-acylation of indoles with aldehydes. The acylation has a broad substrate scope and is compatible with substituents on both the aldehyde and the indole reaction partner. Furthermore, aza-heterocycles such as pyrrole and indazole can also be used as nucleophiles in this reaction providing the corresponding amide congeners in good yield.

A novel one-pot synthesis of N-acylindoles via tandem cycloalkylation- annelation is described. This approach is based on the use of a strong solid-acid catalyst, montmorillonite K-10, and microwave irradiation under solvent-free conditions. The tandem cy
Kinetics and mechanism of the basic hydrolysis of indomethacin and related compounds: A reevaluation

The kinetics of the hydrolysis of indomethacin and related compounds were studied in an alkaline medium at 25°. The pseudo-first-order rate constants were evaluated from log absorbance versus time plots in the ultraviolet. These compounds showed a second-order rate constant at low concentrations of hydroxide ion and a first-order rate constant at higher concentrations of hydroxide ion.

, p. 91 - 92 (2007/10/02)
A simple method for the N-acylation of indole is described.Indole (1) was directly acylated at nitrogen with various carboxylic acids (2) catalyzed by boric acid in moderate yield.
