Respiratory syncytial virus (RSV) is a major cause of respiratory tract infections in infants, young children and adults. 1,2,3,9b-Tetrahydro-5H-imidazo[2,1-a]isoindol-5-ones with general structure 1 were previously identified as promising inhibitors of RSV targeting the fusion glycoprotein. In particular, the introduction of a nitrogen at the 8-position of the tricyclic core yielded lead compounds 2 and 3. Extensive exploration of the R2 group established that certain heterocyclic amides conferred potent RSV A&B activity and a good balance of physicochemical and pharmacokinetic properties. The antiviral activity was found to reside in a single enantiomer and compound 33a, (9bS)-9b-(4-chlorophenyl)-1-(pyridin-3-ylcarbonyl)-1,2,3,9b-tetrahydro-5H-imidazo[1′,2′:1,2]pyrrolo[3,4-c]pyridin-5-one (known as BTA9881), was identified as a candidate for preclinical development.

The acylation of benzene, toluene, and chlorobenzene with cinchomeronic acid anhydride in the presence of AlCl3, has given in each case both possible isomers of the corresponding aroylpyridine carboxylic acid.It was found that the yields of reaction products and their isomeric compositions depend on the conditions of performing the reaction.The intramolecular cyclization on the isomeric keto acids in the presence of 2percent oleum has given 2-azaanthraquinone and chlorine derivatives of it.
