New staves for old barrels: Regioisomeric (12,2 2,33,42,53,62,7 3,82)-p-octiphenyl rods with an NMR tag

The usefulness of rigid-rod p-octiphenyls with the novel 1 2,22,33,42,53,6 2,73,82-motif as staves in rigid-rod beta-barrel pores is evaluated. Comparison with the known characteristics of isomeric pores with the common 13,23,32,4 3,52,63,72,83-sequence indicates that the self-assembly and the supramolecular chirality of rigid-rod beta-barrels are independent of the substitution pattern of the p-octiphenyl stave.

A targetable fluorescent probe for imaging hydrogen peroxide in the mitochondria of living cells

We present the design, synthesis, and biological applications of mitochondria peroxy yellow 1 (MitoPY1), a new type of bifunctional fluorescent probe for imaging hydrogen peroxide levels within the mitochondria of living cells. MitoPY1 combines a chemoselective boronate-based switch and a mitochondrial-targeting phosphonium moiety for detection of hydrogen peroxide localized to cellular mitochondria. Confocal microscopy and flow cytometry experiments in a variety of mammalian cell types show that MitoPY1 can visualize localized changes in mitochondrial hydrogen peroxide concentrations generated by situations of oxidative stress.

Key factors for high diastereo- And enantioselectivity of umpolung cyclizations of aldehyde-containing allylpalladium intermediates

Two palladium/chiral diphosphine-catalyzed umpolung cyc-lizations of aldehyde-containing allylic acetates and allenes with arylboronic acid are fully investigated to establish key factors in their high stereoselectivities. Both cyclization reactions afford cis-disubstituted pyrrolidine and tetrahydrofuran. These occur in high diastereo- and enantioselectivities through a common cationic (Z)-eta1-allylpalladium, toward which a ring strain generated in the cyclization step leading to trans-isomers biases the equilibrium through eta3-eta1-eta3-complex in the former cyclization. Varied diastereoselectivities were observed in the formation of five-membered carbocycles and six-membered heterocycles. These reflect release of a ring strain generated in the cyclization step leading to trans-isomers and a different distribution of the (Z)- and the (E)-eta1-allylpalladium intermediates generated by the oxidative addition of allylic acetates to Pd(0) or carbopalladation of allenes, respectively. A steri-cally demanding substituent at the center of the allyl moiety is necessary for high diastereo- and enantioselectivity. The enantioselectivity of the former cyclization was lowered by the presence of organometallic reductants or reagents, possibly causing the formation of neutral eta1-allylpalladium species. We used a chiral allylic acetate containing (E)-deuterium-labeled alkene to demonstrate that the electrophilic attack of the aldehyde to the allyl ligand occurred on the side where the palladium existed, consistent with the Zimmerman-Traxler transition state.

Mixed ligand, palladium(II) and platinum(II) complexes of tertiary diphosphineswithS-1H benzo[d] imidazole-2-yl benzothioate

Palladium(II) and platinum(II) complexes containing the mixed ligands tertiary diphosphinesdppm. dppp and dppf with Thioester ligand S-1H benzo[d] imidazole-2-yl benzothioate (HSBIBT) have been prepared by the reaction of PdCl2 and PtCl2 with one equiv of tertiary diphosphines ligands to form [Pd(k2-dppf)Cl2], [Pd(k2-dppp)Cl2] and [Pt(k2-dppmCl)Cl2] complexes and then add the ligand HSBIBT to these complexes to form mixed ligand complexes. The prepared complexes have been characterized by single-crystal X-ray diffraction, elemental analysis, magnetic susceptibility, molar conductance, IR spectral data and UV-Visible. The results suggested that the ligand HSBIBT bonded to the metal through N atom and square planner geometries were assigned for the complexes.

The stereocontrolled total synthesis of spirastrellolide A methyl ester. Fragment coupling studies and completion of the synthesis

The spirastrellolides are a novel family of structurally unprecedented marine macrolides which show promising anticancer properties due to their potent inhibition of protein phosphatase 2A. In the preceding paper, a modular strategy for the synthesis of spirastellolide A methyl ester which allowed for the initial stereochemical uncertainties was outlined, together with the synthesis of a series of suitably functionalised fragments. In this paper, the realisation of this synthesis is described. Two alternative coupling strategies were explored for elaborating the C26-C40 DEF bis-spiroacetal fragment: a modified Julia olefination of a C26 aldehyde with a C17-C25 sulfone, and a Suzuki coupling of a C25 trialkylborane with a C17-C24 vinyl iodide, which also required the development of a double hydroboration reaction to install the C23/C24 stereocentres. The latter proved a significantly superior strategy, and was fully optimised to provide a C17 aldehyde which was coupled with a C1-C16 alkyne fragment to afford the C1-C40 carbon framework. The BC spiroacetal was then installed within this advanced intermediate by oxidative cleavage of two PMB ethers with spontaneous spiroacetalisation, which also led to unanticipated deprotection of the C23 TES ether. The ensuing truncated seco-acid was cyclised in high yield to construct the 38-membered macrolactone under Yamaguchi macrolactonisation conditions, suggesting favourable conformational pre-organisation. Exhaustive desilylation provided a crystalline macrocyclic pentaol, revealing much about the likely conformation of the macrolactone in solution. Attachment of the remainder of the side chain proved challenging, potentially due to steric hindrance by this macrocycle; an olefin cross-metathesis to install an electrophilic allylic carbonate and subsequent pi-allyl Stille coupling with a C43-C47 stannane achieved this goal. Global deprotection completed the first total synthesis of (+)-spirastrellolide A methyl ester which, following detailed NMR correlation with an authentic sample, validated the full configurational assignment. A series of simplified analogues of spirastrellolide incorporating the C26-C47 region were also prepared by pi-allyl Stille coupling reactions.
