Nickel(II)- And Silver(I)-Catalyzed C-H Bond Halogenation of Anilides and Carbamates
Kianmehr, Ebrahim,Afaridoun, Hadi
, p. 1513 - 1523 (2020/12/14)
ortho -C-H bond halogenation of anilides and N -aryl carbamates using easily available N -halosuccinimides (NXS) as the active halogenation reagent in the presence of nickel or silver catalyst has been developed. This method provides a new approach to 2-haloanilides and carbamates, which may serve as starting materials for the synthesis of pharmaceutically and biologically active compounds.
ACYLATED SPIROPIPERIDINE DERIVATIVES AS MELANOCORTIN-4 RECEPTOR MODULATORS

Page/Page column 65, (2010/11/27)
Certain novel N-acylated spiropiperidine derivatives are ligands of the human melanocortin receptor(s) and, in particular, are selective ligands of the human melanocortin-4 receptor (MC-4R). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the modulation of MC-4R, such as obesity, diabetes, nicotine addiction, alcoholism, sexual dysfunction, including erectile dysfunction and female sexual dysfunction.
The oxidative bromination and iodination of dimethylacetanilides
Medina, Inmaculada C. Rodriguez,Hanson, James R.
, p. 428 - 429 (2007/10/03)
The oxidative bromination and iodination of the six dimethylacetanilides have been examined; whereas bromination of 2,4-dimethyl- and 2,6-dimethylacetanilides using potassium bromide, sodium tungstate and peracetic acid gave predominantly the 6- and 4-bro
Process for preparing quinazolones

, (2008/06/13)
The present invention provides a process for preparing a quinazolone which comprises the steps of (a) dehydrating a N-acyl beta amino acid in the presence of a dehydration agent and an organic solvent for a sufficient period of time and under suitable temperature and pressure conditions to form an oxazone (b) adding a carboxylic acid and a primary amine salt of a carboxylic acid to said oxazone to form a mixture, (c) distilling azeotropically said mixture for a suitable period of time and under suitable temperature and pressure conditions to substantially remove said dehydration agent and said organic solvent, and (d) heating the product of step (c) for a sufficient period of time and under suitable temperature and pressure conditions to form said quinazolone.

, p. 2681 - 2683 (2007/10/02)
The reaction of acetanilides with tetraalkylammonium polyhalides, such as tetrabutylammonium tribromide, benzyltrimethylammonium tribromide, and benzyltrimethylammonium chlorobromate(1-), in dichloromethane-methanol at room temperature gave bromosubstituted acetanilides in good yields, respectively.
