Lipase-catalyzed kinetic and dynamic kinetic resolution of 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid

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%.

Palladium-catalyzed synthesis of 2,1?-disubstituted tetrahydrofurans from gamma-hydroxy internal alkenes. Evidence for alkene insertion into a Pd-O bond and stereochemical scrambling via beta-hydride elimination

Palladium-catalyzed reactions of gamma-hydroxy internal acyclic alkenes with aryl bromides afford 2,1?-disubstituted tetrahydrofurans in good yields with diastereoselectivities of 3-5:1, The analogous transformations of substrates bearing internal cyclic alkenes afford fused bicyclic and spirocyclic tetrahydrofuran derivatives in good yields with excellent diastereoselectivities (>20:1). A series of deuterium labeling experiments indicate that the origin of the modest diastereoselectivity in reactions of acyclic internal alkene substrates likely derives from a series of reversible beta-hydride elimination and sigma-bond rotation processes that occur following a rare intramolecular alkene syn-insertion into an intermediate Pd(Ar)(OR) complex. In addition, these studies shed light on the chemoselectivity of insertion, suggesting that the alkene inserts into the Pd-O bond in preference to the Pd-C bond.

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.Safety of 4-Bromoisoquinoline, you can also check out more blogs about1532-97-4

Synthesis of bulky and electron-rich MOP-type ligands and their applications in palladium-catalyzed C-N bond formation

A series of 2-dialkylphosphino-2?-alkoxy-1,1?-binaphthyl ligands (6a-c and 8a-c) have been prepared conveniently by a lithium-initiated ring-opening reaction of dinaphthofuran, followed by selective phosphorylation. These compounds displayed a remarkable air and moisture stability, both in solid form and in solution. Application of these phosphine ligands in palladium-catalyzed C-N bond forming reactions revealed the crucial roles of the steric bulk of the substituents on the phosphorus atom governing the catalytic activity. Specifically, 2-di-tert-butylphosphino-2?-isopropoxy-1,1?- binaphthyl (8b) proved to be the most effective for the aminations of aryl halides with primary amines, while the less bulky 2-dicyclohexyl-2?- methoxy-1,1?-binaphthyl (6a) was more effective for the aminations with secondary amines. The steric and electronic effects of the ligands were analyzed to account for these observations.

Effects of 5-aminoisoquinolinone, a water-soluble, potent inhibitor of the activity of poly (ADP-ribose) polymerase, in a rodent model of lung injury

Poly (ADP-ribose) polymerase (PARP), a nuclear enzyme activated by strand breaks in DNA, plays an important role in the tissue injury associated with ischaemia-reperfusion injury and inflammation. The aim of the present study was to evaluate the effects of a novel and potent inhibitor of PARP activity on neutrophil recruitment in the acute inflammation induced by zymosan-activated plasma. Intra-thoracic administration of zymosan-activated plasma leads to an increase in neutrophil infiltration of the lung at 24 hr. The potent PARP inhibitor 5-aminoisoquinolinone (5-AIQ) reduced the degree of lung injury and attenuated the expression of P-selectin and ICAM-1 as well as the recruitment of neutrophils into the injured lung. The up-regulation/expression of P-selectin and ICAM-1 in human endothelial cells exposed to oxidative stress (peroxynitrite) or to a pro-inflammatory cytokine (tumor necrosis factor alpha, TNFalpha) was also attenuated by 5-AIQ. These findings provide the first evidence that the activation of PARS participates in neutrophil-mediated lung injury by regulating the expression of P-selectin and ICAM-1.

Regioselective halogenation of pyridinium N-(benzoazynyl) aminides as a way to produce N-benzyl-alpha-aminobenzoazines

The halogenation of pyridinium N-(benzoazynyl) aminides with N-halosuccinimides provides a mild and regioselective method to functionalize the negatively charged diazine moiety in most cases. In some examples, however, formation of other products is explained. Finally, alkylation of the exocyclic nitrogen and reduction of the N?N bond provides a simple and straightforward strategy to obtain functionalized N-benzyl-benzoazynyl-alpha-amines.
