Stereoselective Hydrogen Transfer Reactions Involving Acyclic Radicals. Tandem Substituted Tetrahydrofuran Formation and Stereoselective Reduction: Synthesis of the C17-C22 Subunit of Ionomycin

The tandem iodoetherification reaction and stereoselective reduction of acyclic redicals has been used in the stereocontrolled synthesis of substituted tetrahydrofurans.Such a tetrahydrofuran intermediate is regioselectively cleaved using Me2BBr to reveal the acyclic array 2 which represents the C17-C22 subunit of ionomycin.In experiments that provide for a better understanding of hydrogen transfer reactions involving acyclic radicals, a significant improvement in the stereoselectivity is observed when the two substituents at the stereogenic center alpha to the radicalare imbedded in a cycle (“cycle effect”).A mechanistic rationale is discussed.

Evolution and status of preparative gas chromatography as a green sample-preparation technique

The present paper reviews recent approaches to preparative capillary gas chromatography (PCGC) covering the period 2010-14. The “green” character of this approach is discussed in relation to the capability to collect chemicals from complex samples, avoiding the consumption of organic solvents that represent a great environmental issue. A discussion is presented regarding critical points in PCGC, mainly related to sample injection, sample capacity, collection system, conditions and sample flushing issues. Following the increasing trend related to the use of multi-dimensional (MD) techniques in recent decades, a section is devoted to the benefits when such an approach is applied in PCGC. One-dimensional and MD applications covering different fields that have appeared in literature since 2010 are described, mainly followed by elucidation steps often performed by nuclear magnetic resonance (NMR), vapour-phase Fourier-transform infrared (FTIR) spectroscopy and mass spectrometric (MS) analyses.

Recent developments of metallic nanoparticle-graphene nanocatalysts

Graphene-based nanomaterials are promising in a wide range of applications due to their unique structural, chemical and physical properties that have recently led to their investigations as co-catalysts and nanoparticle catalyst templates for organic, electrochemical and photochemical reactions. Herein, we present an overview of hybrid metal nanoparticle-graphene catalysts with specific attention to the most recent achievements since 2015. The state-of-the-art of their synthesis and characterization is also summarized, and the synergistic metallic nanoparticle-graphene interactions and their functions in catalysis are discussed. Finally, challenges and future outlooks for this hot area are envisaged.

Process for the preparation of alkyl 1-methylcyclopropanecarboxylate

Disclosed is a 4-step process for the preparation of alkyl esters of 1-methylcyclopropanecarboxylic acid which comprises the steps of (1) converting gamma-butyrolactone to alpha-methyl-gamma-butyrolactone; (2) converting the alpha-methyl-gamma-butyrolactone from step (1) to an alkyl 4-halo-2-methylbutyrate; (3) producing a xylene solution of the alkyl 4-halo-2-methylbutyrate; and (4) contacting the xylene solution of an alkyl 4-halo-2-methylbutyrate from step (3) with an alkali metal alkoxide under conditions of temperature and pressure which causes vaporization of (i) an alkanol as it is formed and (ii) an alkyl 1-methylcyclopropanecarboxylate as it is formed from the alkyl 4-halo-2-methylbutyrate. Also disclosed are processes whereby the alkyl 1-methylcyclopropanecarboxylate, prepared as described above, is converted to 1-methylcyclopropylamine.

Palladium-Catalyzed Directed C(sp3)-H Arylation of Saturated Heterocycles at C-3 Using a Concise Optimization Approach

Saturated heterocycles, such as THFs, pyrrolidines, piperidines and THPs, are essential components of many biologically active compounds. Examples of C-H functionalization on these important ring systems remain scarce, especially at unactivated positions. Here we report the development of conditions for the palladium-catalyzed stereoselective C(sp3)-H arylation at unactivated 3-positions of 5- and 6-membered N- and O-heterocycles with aminoquinoline directing groups. Subtle differences in substrate structures altered their reactivity significantly; and different conditions were required to achieve high yields in each case. Successful conditions were developed using a short empirical optimization approach to cover reaction space with a limited set of variables. Excellent cis-selectivity was achieved in all cases, except for the THP substrate where minor trans-products were formed through a different palladacyclic intermediate. Here, differences in reactivity and selectivity with other directing groups were examined.

Methyllycaconitine analogues have mixed antagonist effects at nicotinic acetylcholine receptors

Bicyclic analogues of methyllycaconitine (MLA), such as 12, have been synthesised that incorporate the C1-OMe substituent present in the natural product. Electrophysiology experiments using Xenopus oocytes expressing nicotinic acetylcholine receptors (nAChRs) were conducted on these analogues and a related tricyclic analogue 2. The most potent compound, 2, was an antagonist at all receptors studied but displayed different antagonist effects at each receptor subtype. This study more clearly defines the biological effects of MLA analogues at nAChRs and demonstrates that these analogues are not selective ligands for the alpha7 nAChR subtype.

Structure-activity relationship of a series of inhibitors of monoacylglycerol hydrolysis – Comparison with effects upon fatty acid amide hydrolase

A series of 32 heterocyclic analogues based on the structure of 2-arachidonoylglycerol (2-AG) were synthesized and tested for their ability to inhibit monoacylglycerol lipase and fatty acid amide hydrolase activities. The designed compounds feature a hydrophobic moiety and different heterocyclic subunits that mimic the glycerol fragment. This series has allowed us to carry out the first systematic structure-activity relationship study on inhibition of 2-AG hydrolysis. The most promising compounds were oxiran-2-ylmethyl (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoate (1) and tetrahydro-2H-pyran-2- ylmethyl (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoate (5). They inhibited cytosolic 2-oleoylglycerol (2-OG) hydrolysis completely (IC50 values of 4.5 and 5.6 muM, respectively). They also blocked, albeit less potently, 2-OG hydrolysis in membrane fractions (IC50 values of 19 and 26 muM, respectively) and anandamide hydrolysis (IC50 values of 12 and 51 muM, respectively). These compounds will be useful in delineating the importance of the cytosolic hydrolytic activity in the regulation of 2-AG levels and, hence, its potential as a target for drug development.
