A dynamic kinetic resolution method for the preparation of enantiopure 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid (R)-2 was developed involving the CAL-B-catalyzed enantioselective hydrolysis of the corresponding ethyl ester (±)-1 in toluene/acetonitrile (4:1) containing 1 equiv of added water and 0.25 equiv of dipropylamine. This method allowed the preparation of (R)-2 (ee = 96%) with 80% isolated yield. The kinetic resolution of (±)-1 in diisopropyl ether at 3 C afforded both enantiomers with ee ?92%.

Research speed reading in 2021. Synthetic Route of 3340-78-1, Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, preparation and modification of special coatings. 3340-78-1, Name is 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, molecular formula is C15H15N. In a Article，once mentioned of 3340-78-1

Four phosphorescent platinum(II) Schiff base complexes are screened for application in visible-light-induced cross-dehydrogenative coupling (CDC) reactions. Preliminary studies show that, among the four platinum(II) complexes, Pt3 is an efficient catalyst for CDC reactions with oxygen as an oxidant. Light irradiation (lambda>420 nm) on a mixture of the PtII complex, tertiary amine, and a variety of nucleophiles (nitroalkanes, ketones, or indoles) under aerobic conditions gives alpha-functionalized tertiary amines in good to excellent yields. The photoluminescence quenching experiment reveals that the CDC reaction is initiated by photoinduced electron transfer from N-phenyltetrahydroisoquinoline to the PtII complex. Further, electron spin resonance (ESR) measurements clearly indicate the formation of superoxide radical anions (O2.-) rather than singlet oxygen (1O2) during the photocatalytic reaction.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Synthetic Route of 3340-78-1. In my other articles, you can also check out more blogs about 3340-78-1

The number of collisions between reactants and catalyst is at a maximum.In a patent, 3340-78-1, name is 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery. category: tetrahydroisoquinoline

Direct oxidation coupling of tertiary amines and dialkyl- or diphenyl-substituted phosphonates was developed. The reaction was mediated by DDQ under room temperature. Various phosphonates and N-aryl tetrahydroisoquinolines were tolerated in this reaction, and alpha-aminophosphonates were obtained with up to 99% yield.

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.category: tetrahydroisoquinoline, you can also check out more blogs about3340-78-1

The ionic liquid 1-butyl-3methylimidazolium tetrafluoroborate [BMIm][BF4] has demonstrated high efficiency when applied as a solvent in the oxidative nitro-Mannich carboncarbon bond formation. The coppercatalyzed cross-dehydrogenative coupling (CDC) between N-phenyltetrahydroisoquinoline and nitromethane in [BMIm][BF4] occurred with high yield under the described reaction conditions. Both the ionic liquid and copper catalyst were recycled nine times with almost no lost of activity. The electrochemical behavior of the tertiary amine substrate and beta-nitroamine product was investigated employing [BMIm][BF4] as electrolyte solvent. The potentiostatic electrolysis in ionic liquid afforded the desired product with a high yield. This result and the cyclic voltammetric investigation provide a better understanding of the reaction mechanism, which involves radical and iminium cation intermediates.
