Assembly of indole-2-carboxylic acid esters through a ligand-free copper-catalysed cascade process.
نویسندگان
چکیده
A straightforward synthesis of indole-2-carboxylic esters was developed through a ligand-free copper-catalysed condensation/coupling/deformylation cascade process from 2-halo aryl aldehydes or ketones with ethyl isocyanoacetate. The reactions proceeded well for most of the 2-iodo-, bromo-, and chloro-substrates under room temperature or mild conditions.

A copper-catalyzed synthesis of 2-(aminomethyl)indole through domino three-component coupling-cyclization has been developed. This reaction proceeds through Mannich-type coupling of 2-ethynylanilines, aldehydes, and secondary amines, followed by hydroamination. This indole formation was applicable to the synthesis of 4-methylene-2,3,4,9-tetrahyro-1H-pyrido[3,4-b]indoles and 5,6,7,8-tetrahydrobe...

The Au(I)-catalysed rearrangement of propargylic esters formed from an ynamide has been studied. The reaction is facile, and when conducted in the presence of a reactive indole nucleophile, leads to a cascade process whereby γ-indolyl α-acyloxyenamides are formed in good yield and excellent E-stereoselectivity.

Rates of acid catalysed decarboxylation in both H,O and D,O a t 25" are reported for indole-3-carboxylic acid and its 2-methyl and 5-chloro-derivatives, and fur indole-3-carboxylic acid in aqueous pyridine buffers a t 60". The experimental data are shown to fitwell with the kinetic expression (Rate = (a + b[L,O+]/(I + c[L30+])} [Substrate]) obtained for the decarboxylation of other aromatic and...

A most effective and less energy demanding method of producing fatty esters, diol esters, by esterifying fatty acids, with neopentyl and ethylenglycol alcohols in the presence of an acidic ion exchange resin catalyst(polyestyrendivinylbenzensulfated) was investigated at elevated temperature. In this process an azeotroping agent, toluene, was used to facilitate continuous removal of water by dis...
