Product Details of 765-70-8, New discoveries in chemical research and development in 2021. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 765-70-8, Name is 3-Methylcyclopentane-1,2-dione, SMILES is O=C1C(C(C)CC1)=O, belongs to quinuclidine compound. In a article, author is BESIDSKY, Y, introduce new discover of the category.
Cyclocondensation of 2-(2-cyano-1,2-diphenylethyl)quinuclidin-3-one 1 in the presence of sulfuric acid gave an intramolecular phenylation instead of lactam formation. The cyclic product was hydrogenated to give 6-carbamoyl-5-phenyl-2,3,4a,5,6,10b-hexahydro-1H-1,4-ethanobenzo- [f]quinoline. On treatment with LiAIH(4) the carbamoyl group was stereospecifically replaced by a hydroxy group. The alcohol was acetylated and the structure was confirmed by X-ray crystallography. The hydroxylation reaction is believed to proceed via a carbonitrile intermediate. In the presence of air the nitrile can be converted to a ketone which is then reduced to the alcohol with an overall retention of configuration.
