New discoveries in chemical research and development in 2021, Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, and development of new chemical products and materials. 18621-17-5, Name is 1-Benzhydrylazetidin-3-ol, SMILES is C3=C(C(N1CC(O)C1)C2=CC=CC=C2)C=CC=C3, in an article , author is Nadirova, Maryana A., once mentioned of 18621-17-5, Safety of 1-Benzhydrylazetidin-3-ol.
It was found that the reaction of 5-arylfurfurilamines with maleic anhydride leads to the formation of 6-aryl-3a,6-epoxyisoindole-7-carboxylic acids (the cyclic form), which in solution are in dynamic equilibrium with N-furfurylmaleinamides (the open form). During the esterification of these tautomeric mixtures with methanol in the presence of a catalytic amount of sulfuric acid, methyl esters of 5-aryl-7a-hydroxy-7-methoxy-3-oxo-2,3,3a,4,7,7a-hexahydro-1H-isoindole-4-carboxylic acids, unexpected cleavage products of the 3a,6-oxo bridge of the cyclic form, are formed diastereospecifically. The structure of the obtained products was confirmed by X-ray structural analysis.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield. If you are hungry for even more, make sure to check my other article about 18621-17-5, Safety of 1-Benzhydrylazetidin-3-ol.
