Triply Threaded [4]Rotaxanes

[4]Rotaxanes featuring three axles threaded through a single ring have been prepared through active metal template synthesis. Nickel-catalyzed sp3-sp3 homocouplings of alkyl bromide "half-threads" through 37- and 38-membered 2,2′:6′,2″-terpyridyl macrocycles generate triply threaded [4]rotaxanes in up to 11% yield. An analogous 39-membered macrocycle produced no rotaxane products under similar conditions. The constitutions of the [4]rotaxanes were determined by NMR spectroscopy and mass spectrometry. Doubly threaded [3]rotaxanes were also obtained from the reactions but no [2]rotaxanes were isolated, suggesting that upon demetalation the axle of a singly threaded rotaxane can slip through a macrocycle that is sufficiently large to accommodate three threads.

A carbon nanotube confinement strategy to implement homogeneous asymmetric catalysis in the solid phase

A readily recyclable asymmetric catalyst has been developed based on the self-assembly of a homogeneous catalyst in a fibrous network of multiwalled carbon nanotubes (MWNTs). Dimerization of an amide-based chiral ligand with a suitable spacer allows for t

17(R),18(S)-Epoxyeicosatetraenoic acid, a potent eicosapentaenoic acid (EPA) derived regulator of cardiomyocyte contraction: Structure-activity relationships and stable analogues

17(R),18(S)-Epoxyeicosatetraenoic acid [17(R),18(S)-EETeTr], a cytochrome P450 epoxygenase metabolite of eicosapentaenoic acid (EPA), exerts negative chronotropic effects and protects neonatal rat cardiomyocytes against Ca 2+-overload with EC50 ≈ 1-2 nM. Structure-activity studies revealed that a cis-Δ11,12- or Δ14,15- olefin and a 17(R),18(S)-epoxide are minimal structural elements for antiarrhythmic activity whereas antagonist activity was often associated with the combination of a Δ14,15-olefin and a 17(S),18(R)-epoxide. Compared with natural material, the agonist and antagonist analogues are chemically and metabolically more robust and several show promise as templates for future development of clinical candidates.

Cyclic Diynes by Alkyne Metathesis

The preparation of α,ω-diynes with methyl groups at the termini (11a-i) is described. The methylene groups between the alkyne units vary between n = 12 (a) and n = 4 (i). Ring closing metathesis with Mo(CO) 6/CF3C6H4OH yielded the monocyclic alkyne 12a with 11a as starting material, whereas 11b-g yielded the cyclic diynes 13b-g. Detailed structural parameters were obtained for 13b and 13c by X-ray crystallography.
