N-formylation of amine using graphene oxide as a sole recyclable metal-free carbocatalyst

Abstract: Graphene oxide (GO), an inexpensive, environment-friendly, and metal-free carbocatalyst, used for the N-formylation of amines is developed. In this reaction, GO shows good activity, selectivity, and recyclability. This strategy has an array of advantages, such as being metal free, without additive, wide-scope protocol, scalable with a low catalyst loading of 3?wt%, use of readily available and recyclable carbocatalyst, and DMF as a readily available formyl source. Furthermore, this strategy provides an avenue for the convenient hydroformylation of various amines. Graphical abstract: [Figure not available: see fulltext.].

Reactivity and mechanistic insight into visible-light-induced aerobic cross-dehydrogenative coupling reaction by organophotocatalysts

With visible-light irradiation, a mild, simple, and efficient metal-free photocatalytic system for the facile construction of sp3-sp 3 C-C bonds between tertiary amines and activated C-H bonds has been achieved. Spectroscopic study and product analysis demonstrate for the first time that photoinduced electron transfer from N-aryl tetrahydroisoquinolines to eosin Y bis(tetrabutylammonium salt) (TBA-eosin Y) takes place to generate TBA-eosin Y radical anion, which can subsequently react with nucleophiles and molecular oxygen. More strikingly, electron spin resonance (ESR) measurements provide direct evidence for the formation of superoxide radical anions (O 2) rather than singlet oxygen (1O 2) during visible-light irradiation. This active species is therefore believed to be responsible for the large rate of acceleration of the aerobic photocatalytic reactions. Light work: With visible-light irradiation (lambda>450 nm), a mild, simple and efficient metal-free photocatalytic system for the facile construction of sp3-sp3 C-C bonds between tertiary amines and activated C-H bonds has been achieved (see scheme). Electron spin resonance measurements offer direct evidence for the formation of superoxide radical anions (O2) during visible-light irradiation. Copyright

18F-Labeled indole-based analogs as highly selective radioligands for imaging sigma-2 receptors in the brain

We have designed and synthesized a series of indole-based sigma2 receptor ligands containing 5,6-dimethoxyisoindoline or 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline as pharmacophore. In vitro competition binding assays showed that all ten ligands possessed low nanomolar affinity (Ki?=?1.79?5.23?nM) for sigma2 receptors and high subtype selectivity (Ki (sigma2)/Ki (sigma1)?=?56?708). Moreover, they showed high selectivity for sigma2 receptor over the vesicular acetylcholine transporter (>1000-fold). The corresponding radiotracers [18F]16 and [18F]21 were prepared by an efficient one-pot, two-step reaction sequence with a home-made automated synthesis module, with 10?15% radiochemical yield and radiochemical purity of >99%. Both radiotracers showed high brain uptake and sigma2 receptor binding specificity in mice.

Structural, mutagenic, and kinetic analysis of the binding of substrates and inhibitors of human phenylethanolamine N-methyltransferase

The X-ray structure of human phenylethanolamine N-methyltransferase (hPNMT) complexed with its product, S-adenosyl-L-homocysteine (4), and the most potent inhibitor reported to date, SK&F 64139 (7), was used to identify the residues involved in inhibitor binding. Four of these residues, Val53, Lys57, Glu219 and Asp267, were replaced, in turn, with alanine. All variants had increased Km values for phenylethanolamine (10), but only D267A showed a noteworthy (20-fold) decrease in its Kcat value. Both WT hPNMT and D267A had similar Kcat values for a rigid analogue, anti-9-amino-6-(trifluoromethyl)benzonorbornene (12), suggesting that Asp267 plays an important role in positioning the substrate but does not participate directly in catalysis. The Ki values for the binding of inhibitors such as 7 to the E219A and D267A variants increased by 2-3 orders of magnitude. Further, the inhibitors were shown to bind up to 50-fold more tightly in the presence of S-adenosyl-L-methionine (3), suggesting that the binding of the latter brings about a conformational change in the enzyme.
