N-Heterocyclic Carbene-Catalyzed Decarboxylative Alkylation of Aldehydes

supporting information, p. 3854 - 3858 (2019/04/25)
We found that N-heterocyclic carbene catalysis promoted the unprecedented decarboxylative coupling of aryl aldehydes and tertiary or secondary alkyl carboxylic acid-derived redox-active esters to produce aryl alkyl ketones. The mild and transition-metal-free reaction conditions are attractive features of this method. The power of this protocol was demonstrated by the functionalization of pharmaceutical drugs and natural product. A reaction pathway involving single electron transfer from an enolate form of Breslow intermediate to a redox ester followed by recombination of the resultant radical pair to form a carbon-carbon bond is proposed.

Page/Page column 70-71, (2016/07/27)
The present invention is directed to amide compounds which are inhibitors of tryptophan hydroxylase (TPH), particularly isoform 1 (TPH1), that are useful in the treatment or prevention of diseases or disorders associated with peripheral serotonin including, for example, gastrointestinal, cardiovascular, pulmonary, inflammatory, metabolic, fibrotic, and low bone mass diseases, as well as cancer.
Ultrasound assisted Friedel-Crafts acylation of aromatics using ferric sulphate as catalyst

The use of ultrasound in the acylation reactions of various aromatics and polyaromatics with different acyl chlorides, in the presence of catalytic amount of ferric sulphate at room temperature, gives good yields of the respective ketones with a short reaction time. A facile and simple synthesis of various aromatic ketones using Friedel-Crafts acylation has been established from the corresponding acid chlorides and aromatic or polyaromatic compounds, respectively under mild reaction conditions with shorter reaction times (30-45 min) and in reasonable yields. This method offers the advantage of low cost and ease of purification of the products because of the small amount of ferric sulphate used in these reactions.
