The synthesis of enantiomerically enriched (R)-2-methyl-1-tetralone 1 (64% e.e.) was achieved through protonation of its lithium enolate 3 using a C 2-symmetrical bis-sulfonamide 5d as an internal proton source. Access to the complementary (S)-enantiomer 1 (45% e.e.) can be achieved using an external quench strategy involving acetic acid as the external proton source.

Enantioselective, potentiometric membrane electrodes (EPMEs) based on carbon paste impregnated with different maltodextrins {dextrose equivalent (DE) 4.0-7.0 (I), 13.0-17.0 (II) and 16.5-19.5 (III)} as chiral selectors for the assay of S-perindopril is described. The proposed electrodes could be reliably employed in the assay of S-perindopril raw material and from its pharmaceutical formulation, Coversyl tablets. The electrode based on maltodextrin (I) showed the best enantioselectivity and time-stability. The surfaces of the electrodes are easily renewable by simply polishing on an alumina paper.

Carbon-13 NMR line shape analysis of the lithium isotopomers of 2,4,6-tri-tert-butylphenyllithium monomer, 4, complexed to THF establishes that electric quadrupole induced relaxation of 7Li is responsible for partial averaging of 1J(13C,7Li). The dynamics of intramolecular carbon-lithium bond exchange between monomers of 4 in THF solutions have been monitored by NMR line shape analysis, signal averaging of 1J(13C,6Li) observed above 240 K, yielding activation parameters of DeltaH? and DeltaS? of respectively 14.4 kcal/mol and 7 eu. All except the meta carbons of mesityllithium, 5, monomer tridentately complexed to N,N?,N?,N?,N?-pentamethyldiethylenetriamine, PMDTA, are magnetically non-equivalent at 184 K, supporting an asymmetric structure in which lithium is chiral. With increasing temperature above 184 K the shifts between the ortho ring carbons, the ortho methyls, and two doublets due to methylenes progressively average to single lines at their respective centers, the result of increasingly fast rotation around the carbon-lithium bond, with resulting activation parameters of DeltaH? and DeltaS? of respectively 5 kcal/mol and -21 eu. It is proposed that rotation is chemically driven, the result of Li, N reversible dissociation accompanied by an uptake by Li of one THF molecule.

Concern is growing regarding the prospects of achieving the global elimination of lymphatic filariasis (LF) by 2020. Apart from operational difficulties, evidence is emerging which points to unique challenges that could confound achieving LF elimination as extinction targets draw near. Diethylcarbamazine (DEC)-medicated salt may overcome these complex challenges posed by the endgame phase of parasite elimination. We calibrated LF transmission models using Bayesian data-model assimilation techniques to baseline and follow-up infection data from 11 communities that underwent DEC salt medication. The fitted models were used to assess the utility of DEC salt treatment for achieving LF elimination, in comparison with other current and proposed drug regimens, during the endgame phase. DEC-medicated salt consistently reduced microfilaria (mf) prevalence from 1% mf to site-specific elimination thresholds more quickly than the other investigated treatments. The application of DEC salt generally required less than one year to achieve site-specific LF elimination, while annual and biannual MDA options required significantly longer durations to achieve the same task. The use of DEC-medicated salt also lowered between-site variance in extinction timelines, especially when combined with vector control. These results indicate that the implementation of DEC-medicated salt, where feasible, can overcome endgame challenges facing LF elimination programs.

(Figure Presented) Copper or nickel? The depicted CuII salen complex, an active-site model of galactose oxidase (GO), is a localized radical in the solid state with a quinoid distribution of bond lengths in one ring. While the ligandradical structure is not metal-dependent, the composition of the radical SOMO is. This feature may explain the much lower reactivity of the Ni complex and nature’s preference for a CuII center in CO.

Divergent catalytic reactions provide quick access to diverse molecular scaffolds through controlled reaction pathways by tuning the catalytic conditions, especially changing auxiliary ligands and/or counterions. This study presents a computational study of Au(I)-catalyzed regiodivergent cycloisomerizations of boron-containing alkynyl epoxides toward C2- and C3-borylated furans. The calculations clarified the mechanistic details of the reaction and the regiodivergence induced by two gold catalysts. The proposed catalytic cycle involves two major stages: ring expansion of alkynyl epoxide accompanied by B(MIDA) group migration to form a m-boron furyl heterocyclic intermediate and a formal 1,2-H or a 1,2-B migration to form a C3- or C2-borylated furan. The former is identified as the bottleneck of the reaction, which proceeds via sigma activation of the oxirane moiety rather than pi activation of the alkynyl moiety proposed in experimental work, and the latter controls the regiodivergence. Calculations show that the counterion and ligand in the gold catalyst play a less important role in the ring expansion, but they are crucial for the divergent formation of borylated furans: an OTf- counterion with an (ArO)3P ligand favors the 1,2-H migration, leading to the formation of C3-borylated furan, whereas an SbF6- anion with an IPr ligand promotes the 1,2-B migration, supporting the predominant formation of C2-borylated furan. The theoretical results rationalize the observed regioselectivity and provide key insights into the mechanism of the migratory cycloisomerization of boron-containing alkynyl epoxides.
