چکیده

The Grignard, Wittig, Tebbe, Horner-Emmons, and Reformatsky reactions of the 4-oxoproline esters gave the corresponding 4-alylated or 4-alkylidenated products, respectively. The products were properly treated with bases to cause aromatization, giving 4-substituted pyrrole-2-carboxylic acid esters such as methyl 4-methylpyrrole-2-carboxylate, which is a trail pheromone of Atta texana.

A new series of 5-substituted-3-methylsulfanyl-1-(2,4-dinitro phenyl)-1H-pyrazole-4-carboxylic acid ethyl esters were synthesized by reacting the amino group of 5-amino-3-methylsulfanyl-1-(2,4-dinitro phenyl)-1H-pyrazole-4carboxylic acid ethyl ester with acid anhydrides, acid chlorides and phenyl dithiocarbamates. The title compounds were investigated for analgesic, anti-inflammatory and ulcero...

Palladium-catalyzed C–N and C–O bond formation of N-substituted 4-bromo-7-azaindoles with amides, amines, amino acid esters and phenols

Simple and efficient procedures for palladium-catalyzed cross-coupling reactions of N-substituted 4-bromo-7-azaindole (1H-pyrrole[2,3-b]pyridine), with amides, amines, amino acid esters and phenols through C-N and C-O bond formation have been developed. The C-N cross-coupling reaction of amides, amines and amino acid esters takes place rapidly by using the combination of Xantphos, Cs(2)CO(3), d...
