Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials. 1235-74-1, Name is (1R,4aS,10aR)-methyl 7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthrene-1-carboxylate, molecular formula is C21H30O2, belongs to isothiazole compound. In a document, author is Popova, Maria V., introduce the new discover, Application of 1235-74-1.
We have introduced a strategy for the construction of spirocycloalkane 1 lambda(6)-isothiazolidine-1,1,4-triones through the mesylation of 1-aminocyclopentane-, 1-aminocyclohexane-, and 1-aminocycloheptanecarboxylic acid esters with methanesulfonylchloride followed by alkylation with methyl iodide and consequent cyclization in the presence of potassium tert-butoxide in N,N-dimethylformamide. The spirocycloalkane 4-amino-2,3-dihydro-1H-1 lambda(6)-isothiazole-1,1-diones were prepared via mesylation of N-methylated 1-aminocyclopentyl-, 1-aminocyclohexyl-, and 1-aminocycloheptyl carbonitriles followed by treatment of obtained N-(1-cyanocycloalkyl)-N-methylmethanesulfonamides with potassium tert-butoxide in N,N-dimethylformamide. The spiro 4-amino-2,3-dihydro-1H-1 lambda(6)-isothiazole-1,1-diones were converted into the target spiro 1 lambda(6)-isothiazolidine-1,1,4-triones by acid-catalyzed hydrolysis. The structure of a target spiro compound and its isolated key intermediate was confirmed by X-ray diffraction study. The interaction of spiro 1 lambda(6)-isothiazolidine-1,1,4-triones with N,N-dimethylformamide dimethyl acetal leads to the formation of spiro 5-[(Z)-(dimethylamino)methylidene]-1 lambda(6)-isothiazolidine-1,1,4-triones.
Application of 1235-74-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect. I hope my blog about 1235-74-1 is helpful to your research.
