Research speed reading in 2021. Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent，Which mentioned a new discovery about COA of Formula: C15H15N, molcular formula is C15H15N, introducing its new discovery. , COA of Formula: C15H15N
(S)-(+)-1-Phenyl-1,2,3,4-tetrahydroisoquinoline, which is the key intermediate in preparing the urinary antispasmodic drug solifenacin, was racemized in quantitative yield by a simple one-pot procedure through N-chlorination with trichloroisocyanuric acid, conversion of the N-chloroamine into the imine hydrochloride, and reduction of the imine double bond. The racemized amine was successfully resolved by d-(-)-tartaric acid obtaining (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline in 81% yield and with 96.7% ee and, from the crystallization mother liquors, the R enriched form. This was racemized by the same one-pot process and resolved by d-(-)-tartaric acid with the same efficiency. Such an approach to the racemization of 1-phenyl-1,2,3,4- tetrahydroisoquinoline can be industrially useful to recycle the waste R enantiomer resulting from the classical resolution used to obtain the S enantiomer on a large scale.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C15H15N, you can also check out more blogs about22990-19-8
