Palladium-catalyzed transfer semihydrogenation of alkynes using H2O as the hydrogen source and Mn reducing reagent is developed, affording cis- trans-alkenes selectively under mild conditions. In addition, this method provides an efficient way to access various cis-1,2-dideuterioalkenes trans-1,2-dideuterioalkenes by D2O instead H2O.

The use of deuteration in medicinal chemistry has exploded the past years, and FDA recently approved first deuterium-labeled drug. Precision goes beyond pure simple amelioration pharmacokinetic parameters a drug might provide an opportunity when facing problems terms metabolism-mediated toxicity, interactions, low bioactivation. deuterium is even broader, offering to lower degree epimerization, reduce dose coadministered boosters, discover compounds where basis for mechanism action. Nevertheless, designing, synthesizing, developing successful deuterated far from straightforward, translation concept practice often unpredictable. This Perspective provides overview recent developments deuteration, with focus on clinical candidates, highlights both opportunities challenges this strategy.

Organic compounds labeled with hydrogen isotopes play a crucial role in numerous areas, from materials science to medicinal chemistry. Indeed, while the replacement of by deuterium gives rise improved absorption, distribution, metabolism, and excretion (ADME) properties drugs enables preparation internal standards for analytical mass spectrometry, use tritium-labeled is key technique all along drug discovery development pharmaceutical industry. For these reasons, interest new methodologies isotopic enrichment organic molecules extent their applications are equally rising. In this regard, Review intends comprehensively discuss developments area over last years (2017–2021). Notably, besides fundamental isotope exchange (HIE) reactions isotopically analogues common reagents, plethora reductive dehalogenative deuteration techniques other transformations incorporation emerging now part labeling toolkit.

The ability to differentiate between highly similar C–H bonds in a given molecule remains fundamental challenge organic chemistry. In particular, the lack of sufficient steric and electronic differences located distal functional groups has prevented development site-selective catalysts with broad scope. An emerging approach circumvent this obstacle is utilize distance target bond coordinating group, along geometry cyclic transition state directed activation, as core molecular recognition parameters multiple bonds. Perspective, we discuss advent recent advances concept. We cover wide range transition-metal-catalyzed, template-directed remote activation reactions alcohols, carboxylic acids, sulfonates, phosphonates, amines. Additionally, review eminent examples which take advantage non-covalent interactions achieve regiocontrol. Continued advancement distance- geometry-based differentiation for regioselective functionalization may lead ultimate realization editing: freedom modify molecules at any site, order.

Abstract Tritium labelling is a critical tool for investigating the pharmacokinetic and pharmacodynamic properties of drugs, autoradiography, receptor binding occupancy studies 1 . gas preferred source tritium preparation labelled molecules because it available in high isotopic purity 2 The introduction labels from commonly achieved by heterogeneous transition-metal-catalysed tritiation aryl (pseudo)halides. However, catalysts such as palladium supported on carbon operate through reaction mechanism that also results reduction other functional groups are prominently featured pharmaceuticals 3 Homogeneous can react chemoselectively with (pseudo)halides but have not been used hydrogenolysis reactions because, after required oxidative addition, they cannot split dihydrogen 4 Here we report homogenous well defined, molecular catalyst. We show how thianthrene leaving group—which be introduced selectively into late-stage C–H functionalization 5 —differs its coordinating ability to relevant palladium(II) conventional enable previously unrealized catalysis dihydrogen. This distinct reactivity combined chemoselectivity defined catalyst enables small-molecule contain functionality may otherwise tolerated catalysts. does require an inert atmosphere or dry conditions therefore practical robust execute, could immediate impact discovery development pharmaceuticals.
