Enantioselective Synthesis of Tertiary alpha,alpha-Diaryl Carbonyl Compounds Using Chiral N,N?-Dioxides under Umpolung Conditions

Br¡ãnsted acid-catalyzed addition of the chiral N,N?-dioxide into ynamides generated enolonium ions in situ which underwent enantioselective alkylation by indoles, pyrroles, and phenols, without racemization of the formed tertiary center. This external oxidant approach allows for the use of unmodified nucleophiles and does not leave trace groups from the oxidant, which significantly increases the synthetic efficiency and the product diversity. Furthermore, the byproduct of the N,N?-dioxide could be efficiently recycled into an optically pure form.

An analytical perspective on favoured synthetic routes to the psychoactive tryptamines

Many tryptamine derivatives are known to induce altered states of consciousness and are increasingly of interest in forensic and neurobiological studies. The analytical chemistry of certain synthetic routes to the tryptamines is discussed and likely side products and impurities identified, where literature reports are available. Recent examples from the authors’ laboratory are presented to highlight future prospects and implications for analytical procedures. The aim of this review is to provide the analytical chemist with the foundation chemistry and some analytical targets to be able to undertake direct characterisation of products and intermediates. These might become available from interdiction of clandestine operations in a forensic environment or during the synthesis of the tryptamines for investigative neurobiological and clinical procedures.

Rhodium (III)-catalyzed regioselective direct C-2 alkenylation of indoles assisted by the removable N-(2-pyrimidyl) group

The C-2-alkenylindole unit is a key component of numerous natural products and pharmacophores. However, the intermolecular direct construction of the core structural motif remains challenging in organic synthesis. Here we report a new, efficient, and versatile methodology for the synthesis of C-2-alkenylindoles through rhodium (III)-catalyzed direct C-H functionalization of indoles with acrylates under air by employing a metal-directing group strategy. This strategy gives a rare selectivity for the alkenylation N-(2-pyrimidyl)indoles at the C-2 position and provides the functionalized C-2- alkenylindoles under mild conditions with broad substrate tolerance. An expansion of the methodology has also been demonstrated to, for example, the direct alkenylation of pyrrole and facile deprotection of the pyrimidyl group. All the results suggest that this methodology could be served as a highly attractive alternative for the direct construction of biologically important C-2-alkenylindoles.

The Concise Synthesis of Unsymmetric Triarylacetonitriles via Pd-Catalyzed Sequential Arylation: A New Synthetic Approach to Tri- and Tetraarylmethanes

The selective synthesis of multiarylated acetonitriles via sequential palladium-catalyzed arylations of chloroacetonitrile is reported. The three aryl groups are installed via a Pd-catalyzed Suzuki-Miyaura cross coupling reaction followed by back-to-back C-H arylations to afford triarylacetonitriles in three steps with no over-arylation at any step. The triarylacetonitrile products can be converted into highly functionalized species including tetraarylmethanes. This new strategy provides rapid access to a variety of unsymmetrical tri- and tetraarylmethane derivatives from simple, readily available starting materials. (Chemical Presented)

A biomass involved rhodium-catalyzed carbonylative synthesis of furfuryl esters and tertiary amides has been developed. 5-Hydroxymethylfurfural (HMF) was used as both substrate and CO surrogate for the first time in a carbonylation reaction, and both alkyl and aryl iodides were tolerated well to afford the desired furfuryl esters in moderate to good yields. In addition, furfural was also utilized as a CO source for the synthesis of tertiary amides.

Targeted and untargeted characterisation of free and glycosylated simple phenols in cocoa beans using high resolution-tandem mass spectrometry (Q-Orbitrap)

Free simple phenols have positive effects on health and influence the organoleptic profile of cocoa products, contributing towards defining their aroma and nutritional properties. Glycosidically bound simple phenols can be hydrolysed during the production phase to the corresponding free forms, and thus potentially contribute to the final sensory profile. In this work, 60 samples of Forastero cocoa beans from all over the world were analysed, combining on-line solid phase extraction (SPE) clean-up with ultra-high performance liquid chromatography (UHPLC), coupled with high resolution mass spectrometry. Operating in negative ion mode and with a heated electrospray, 62 simple phenols were measured, of which four were glucosidic precursors, with quantification limits ranging from 0.04 to 40?mg?kg?1, calibration R2 of 0.99 for over 93% of compounds, and precision (R.S.D.%) always lower than 12%. On the basis of accurate mass, isotope pattern and MS/MS spectrum, 32 monoglycosylated simple phenols such as hexoside and pentoside precursors, and 14 diglycosylated simple phenols such as hexoside-hexoside, hexoside-pentoside and pentoside-hexoside precursors, were tentatively identified. The untargeted approach was validated using 3 glucosidic precursors synthesized by an external supplier.
