Photoredox-mediated remote C(sp3)-H heteroarylation of free alcohols

We report an efficient and economical method for remote delta C(sp3)-H heteroarylation of free aliphatic alcohols using a hypervalent iodine PFBI-OH oxidant under photoredox catalysis. The reaction sequence involves in situ alcoholysis of PFBI-OH with alcohol, generation of an alkoxy radical intermediate by SET reduction, 1,5-HAT, and Minisci-type C-C bond formation. This method uses a slight excess of alcohols, can facilitate reaction at delta methyl and methylene positions, and has been successfully applied to modification of complex drug molecules.

1,2-Dihydroisoquinoline-N-acetic acid derivatives as new carriers for brain-specific delivery II: Delivery of phenethylamine as model drug

N-alkyloxycarbonylmethyl-1,2-dihydroisoquinolin-4-carboxylic acid derivatives 7 a-c were synthesized as new carriers for brain specific delivery. The design of the carrier systems are based on sequential hydrolysis at the acetic acid ester group linked to dihydroisoquinoline nitrogen followed by ring oxidation and formation of quaternary isoquinolinium derivatives which are then hydrolyzed to release the drug. Once the carrier system is administered, a sequential enzymatic process will take place resulting in significant increase in its rate of oxidation, the key factor in brain specific delivery. The chemical stability of the synthesized carrier system was investigated in aqueous buffer solutions and ferricyanide reagent and proofed to be quite stable against hydration and oxidation during formulation and storage. Furthermore, enzymatic stability was also investigated in 80% human plasma and 20% rabbit brain homogenate. Both oxidation and hydrolysis were found to take place; however, hydrolysis was the major route. In vivo distribution of the ethyl ester derivative 7 b was studied in rats and showed that the concentration of the quaternary product is increasing in the brain and cleared from blood with time.

Palladium-catalyzed carbonylation of aryl, alkenyl, and allyl halides with phenyl formate

Highly efficient palladium-catalyzed carbonylation of aryl, alkenyl, and allyl halides with phenyl formate is reported. This procedure does not use carbon monoxide and affords one-carbon-elongated carboxylic acid phenyl esters in excellent yields. The reaction proceeds smoothly under mild conditions and tolerates a wide range of functional groups including aldehyde, ether, ketone, ester, and cyano groups. Furthermore, a variety of heteroaromatic bromides can be converted to the corresponding phenyl esters in high yields.

Water and Sodium Chloride: Essential Ingredients for Robust and Fast Pd-Catalysed Cross-Coupling Reactions between Organolithium Reagents and (Hetero)aryl Halides

Direct palladium-catalysed cross-couplings between organolithium reagents and (hetero)aryl halides (Br, Cl) proceed fast, cleanly and selectively at room temperature in air, with water as the only reaction medium and in the presence of NaCl as a cheap additive. Under optimised reaction conditions, a water-accelerated catalysis is responsible for furnishing C(sp3)?C(sp2), C(sp2)?C(sp2), and C(sp)?C(sp2) cross-coupled products, in competition with protonolysis, within a reaction time of 20 s, in yields of up to 99 %, and in the absence of undesired dehalogenated/homocoupling side products even when challenging secondary organolithiums serve as the starting material. It is worth noting that the proposed protocol is scalable and the catalyst and water can easily and successfully be recycled up to 10 times, with an E-factor as low as 7.35.

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

Palladium-catalysed direct monoarylation of bithiophenyl derivatives or bis(thiophen-2-yl)methanone with aryl bromides

Arylated bithiophenes, which are useful compounds due to their coordination and/or physical properties, can be easily prepared by palladium-catalysed C-H bond activation of heteroaromatics followed by arylation using electron-deficient aryl bromides. A variety of 5-arylated 2,2?- bithiophenyl derivatives have been prepared. Good yields were generally obtained by using the air-stable [PdCl(dppb)(C3H5)] complex as catalyst. A range of functions on the aryl bromide, such as acetyl, formyl, ester, nitrile, trifluoromethyl, fluoro and hydroxyalkyl, are tolerated.
