(5R,6S)-6-Acetoxy-5-hexadecanolide (MOP) is the oviposition pheromone of the mosquito Cx. quinquefasciatus, a vector of pathogens causing a variety of tropical diseases. We describe and evaluate herein three syntheses of MOP starting from mannitol-derived (3R,4R)-hexa-1,5-diene-3,4-diol. This C2-symmetric building block is elaborated through bidirectional olefin metathesis reactions into 6-epi-MOP, which was converted into MOP via Mitsunobu inversion. The shortest of the three routes makes use of two sequential cross-metathesis reactions and an assisted tandem catalytic olefin reduction, induced by an in situ conversion of a Ru-carbene to a Ru-hydride.

A large covalent cage incorporating two porphyrins attached by four long and flexible polyether chains each bearing two 3-pyridyl ligands was synthesized from a DABCO-templated olefin metathesis reaction. The X-ray structure of the cage with the DABCO coordinated inside the cavity to the two zinc(ii) porphyrins reveals a highly symmetric structure.

The fundamental role played by actin In the regulation of eukaryotic cell maintenance and motility renders it a primary target for small-molecule intervention. in this arena, a class of potent cytotoxic cyclodepsipeptide natural products has emerged over the last quarter-century to stimulate the fields of biology and chemistry with their unique actin-stabilizing properties and complex peptide-polyketide hybrid structures. Despite considerable research effort, a structural basis for the activity of these secondary metabolites remains elusive, not least for the lack of high-resolution structural data and a reliable synthetic route to diverse compound libraries. in response to this, an efficient solid-phase approach has been developed and successfully applied to the total synthesis of Jasplakinolide and chondramide C and diverse analogues. The key macrocylization step was realized using ruthenium-catalyzed ring-closing metathesis (RCM) that in the course of a library synthesis produced discernible trends in metathesis reactivity and E/Z-selectivity, After optimization, the RCM step could be operated under mild conditions, a result that promises to facilitate the synthesis of more extensive analogue libraries for structure-function studies. The growth inhibitory effects of the synthesized compounds were quantified and structure-activity correlations established which appear to be in good alignment with relevant biological data from natural products. in this way a number of potent unnatural and simplified analogues have been found. Furthermore, potentially important stereochemical and structural components of a common pharmacophore have been identified and rationalized using molecular modeling. These data will guide in-depth mode-of-action studies, especially into the relationship between the cytotoxicity of these compounds and their actin-perturbing properties, and should inform the future design of simplified and functionalized actln stabilizers as well.

Application of 246047-72-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium.

Synthetic approaches to (1RS,2SR,6SR)-7-arylmethyl-2-alkoxymethyl-4,7-diaza-9-oxabicyclo[4.3.0]nonan-8-ones, potentially selective muscarinic M1 receptor agonists, by hydration of 1,2,5,6-tetrahydropyridines were investigated. 3-Substituted N-tosyl-1,2,5,6-tetrahydropyridines were prepared by ring-closing metathesis (RCM). The direct hydration of these by hydroboration-oxidation was not usefully selective, but cis-3-hydroxymethyl-4-tert-butyldimethylsilyloxy-N-tosylpiperidine was prepared from 3-hydroxymethyl-N-tosyl-1,2,5,6-tetrahydropyridine by epoxidation, mesylation, reductive elimination, silylation and hydroboration-oxidation. Problems were encountered during attempts to prepare 3-alkoxymethyl-1,2,5,6-tetrahydropyridines with protected amino and cyclobutyl substituents at C5 by ring-closing metathesis, perhaps because of steric hindrance. Nevertheless interesting chemistry was encountered during the synthesis of the RCM precursors including a novel coupling via a 2-ethenyl-N-nosylaziridine and the formation of an oxaazathiocin by an intramolecular substitution of the nitro group of an N-nosyl protected amine by a proximate hydroxyl substituent.

Templation is a well-known strategy for the selective generation of complex products. Ring-closing metathesis, catalyzed by well-characterized Ru and Mo catalysts, is a powerful method for C{double bond, long}C bond formation and has certainly developed into one of the most important modern reactions in organic synthesis and in polymer chemistry. Despite the extensive research on this reaction, the use of organometallic containing substrates is not well-studied. Here, we give a detailed account of our ongoing efforts to employ ring-closing metathesis with bis(alpha-olefin) substituted pyridines in the presence of trimeric metallopincer templates for the selective synthesis of macroheterocycles with ring sizes up to 81 atoms.

We report a systematic study of the allylation of ortho-substituted benzaldehydes under catalysis of a Lewis base (N, Ndioxide), a Lewis acid (Keck allylation), and a Bronsted acid. ortho-Halobenzaldehydes were used as the aldehydic substrates, and special attention was paid to ortho-vinyl and alkynyl benzaldehydes, which might serve as interesting synthons for the preparation of more complex chiral compounds. Similar enantioselectivities were achieved under catalytic conditions. In the case of ortho-halobenzaldehydes, Lewis base catalysis proved to be more efficient, and the highest asymmetric induction for allylation of ortho-fluorobenzaldehyde reached 82% ee, which is comparable to other used catalytic conditions. In cases of ortho-vinylbenzaldehyde, the Keck allylation provided the product in 88% ee. An enantioenriched homoallylic alcohol was used as the starting material for the synthesis of a sertraline intermediate.

Several alpha-configured C-sialosides were synthesised by cross metathesis and further synthetic derivatisation to obtain ligands for Trypanosoma cruzi trans-sialidase (TcTS), a key enzyme in Chagas disease. Affinities of these compounds to immobilised TcTS were measured by surface plasmon resonance (SPR). The KD values thus obtained are in the lower millimolar range and will be discussed. The results show the importance of addressing Tyr119 and Trp312 side chains of TcTS in target oriented ligand synthesis, since these amino acids constitute the acceptor binding region in the active site of TcTS. The best ligand showed a significant decrease of TcTS activity in a preliminary NMR based inhibition assay.

(Chemical Equation Presented) Oxygen knocks it out: Olefin metathesis catalysts without steric hindrance in the ortho positions of the N-aryl substituents can be transformed into catalytically inactive ruthenium complexes through C-H activation (see scheme). This process presumably proceeds by a pericyclic reaction and is rendered irreversible by oxygen.
