When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. In an article, author is Renaud, T, once mentioned the application of 99-61-6, Name is 3-Nitrobenzaldehyde, molecular formula is C7H5NO3, molecular weight is 151.12, MDL number is MFCD00007249, category is thiomorpholine. Now introduce a scientific discovery about this category, Quality Control of 3-Nitrobenzaldehyde.
The electrochemical cyanation of various six-membered N-(2-nitrophenyl) heterocyclic amines, including piperidine, morpholine, thiomorpholine, and N-Boc-protected piperazine derivatives, was investigated. The expected cyanoamines 5 were obtained in good yields and subjected to catalytic hydrogenation to afford the corresponding cyclic amidine N-oxides 6. The reductive cyclization proceeded through the formation of a hydroxylamine, which cyclized onto the cyano moiety. The stereoselectivity of the cyclization reaction was studied for the cases both of trans-5f, in which the substituent was axial and the 4-methyl substituent equatorial, and of cis-5f, in which both the 2-cyano and the substituents were equatorial. The expected tetrahydroquinoxalines 3 were conveniently prepared in a following step by the catalytic hydrogenation of cyclic amidines 6 in the presence of Pearlman’s catalyst at five atmospheres of hydrogen pressure.
In the meantime we’ve collected together some recent articles in this area about 99-61-6 to whet your appetite. Happy reading! Quality Control of 3-Nitrobenzaldehyde.
