Photopolymerization using maleimides as photoinitiators

The photoinitiated polymerization of 1,6-hexanedioldiacrylate (HDDA) has been investigated using a variety of N-substituted maleimides to initiate the polymerization process upon exposure to light from a mercury lamp. When readily abstractable hydrogens are available, the polymerization is rapid. A maleimide with a carbonate group attached gave the greatest exotherm for HDDA polymerization. Copyright

An Optimized Glutamate Receptor Photoswitch with Sensitized Azobenzene Isomerization

A new azobenzene-based photoswitch, 2, has been designed to enable optical control of ionotropic glutamate receptors in neurons via sensitized two-photon excitation with NIR light. In order to develop an efficient and versatile synthetic route for this molecule, a modular strategy is described which relies on the use of a new linear fully protected glutamate derivative stable in basic media. The resulting compound undergoes one-photon trans-cis photoisomerization via two different mechanisms: direct excitation of its azoaromatic unit and irradiation of the pyrene sensitizer, a well-known two-photon sensitive chromophore. Moreover, 2 presents large thermal stability of its cis isomer, in contrast to other two-photon responsive switches relying on the intrinsic nonlinear optical properties of push-pull substituted azobenzenes. As a result, the molecular system developed herein is a very promising candidate for evoking large photoinduced biological responses during the multiphoton operation of neuronal glutamate receptors with NIR light, which require accumulation of the protein-bound cis state of the switch upon repeated illumination.

One-pot synthesis of polyurethane-imides with tailored performance from castor and tung oil

Herein, castor and tung oil-based polyurethane-imides with tailored thermal and mechanical performance were developed by a one-pot method. First, tung oil (TO) was transformed into eleostearic acid diethanol amide (EADEA) by methyl-esterification and amidation. The resulting EADEA was then mixed with castor oil (CO), N-(2-hydroxyethyl)-maleimide (HEMI) and isophorone diisocyanate to prepare biobased polyurethane-imides. The formation of Diels-Alder (DA) adducts from EADEA and HEMI during the curing process was determined by proton nuclear magnetic resonance (1H NMR) and Fourier transform infrared spectroscopy (FTIR). The effect of DA adducts contents on the thermal and mechanical properties of corresponding polymers was investigated. The results show that the introduction of TO-maleimide DA adducts significantly increases the glass transition temperature, tensile strength, Young’s modulus and gel content of the resulting polyurethanes. The highest tensile strength of the resulting polymers can reach 48.2 MPa. Besides, the thermal stability was also improved with the incorporation of imide groups. This technique reported here demonstrates several advantages, such as one-pot synthesis, high bio-renewable content, low cost and tunable performance, and it is promising to find application in coatings, adhesives and so on.

The stereodynamics of macrocyclic succinimide-thioethers

Maleimide-thiol coupling is a popular bioconjugation strategy, but little is known about the stereoselectivity and the stereodynamics of the succinimide thioether formed in a biopolymer environment. We used thiol 1,4-addition for the macrocyclisation of 5 designed pentapeptides with the ringsize of hexapeptides because they incorporate the succinimide thioether (4-8). Both succinimide diastereomers are observed in the constrained macrocyclic rings in each case. In spite of the low diastereoselectivity of the macrocyclisation reaction, there is a significant influence of the amino acid environment on the epimerization rate of the succinimide. Its half life can be as short as several hours at room temperature when Gly is the amino acid following the succinimide (peptide 8). On the contrary, no epimerization is detectable even after several weeks in the case of d-Phe C-terminal to the succinimide in peptide 4. Already the small selection of examples shows how big the differences in epimerization rates can be and that the local environment has a significant influence. The variation of amino acids in the vicinity of the ligation site points the way towards the synthesis of bioconjugates which are obtained as stable and separable diastereomers.

Enantioselective synthesis of stephacidin B

We describe an enantioselective synthetic route to the antiproliferative alkaloid stephacidin B (1) proceeding in 18 steps and 4.0% yield from 4,4-(ethylenedioxy)-2,2-dimethylcyclohexanone (3). Key features of the synthetic sequence include the use of the Corey-Bakshi-Shibata (CBS) reduction to introduce asymmetry early in the synthetic route, use of the novel electrophile N-(tert-butoxycarbonyl)-5-(isopropylsulfonyloxymethyl)-2,3-dihydropyrrole in a stereoselective enolate alkylation, a diastereoselective Strecker-type addition of hydrogen cyanide to an N-Boc enamine substrate in the solvent hexafluoroisopropanol, platinum-catalyzed nitrile hydrolysis under neutral conditions, cyclization of an acylamino radical intermediate to form the diketopiperazine core of stephacidin B, and implementation of a convergent procedure for introduction of the key 3-alkylidene-3H-indole 1-oxide functional group in the final stage of the route to prepare the structure 2, previously proposed to be the fungal metabolite avrainvillamide (17 steps, 4.2% yield). We observed that synthetic (-)-2 dimerized in the presence of triethylamine to form (+)-stephacidin B (>95%). We also obtained evidence that 2 can form 1 under mild conditions, and that 2 reacts with nucleophiles, such as methanol, by conjugate addition. Copyright

A Catenane as a Mechanical Protecting Group

Mechanophores (mechanoresponsive molecules) offer great promises for the development of smart force-responsive materials. The activity of a mechanophore can be tuned by altering its structure or the composition of the actuating polymer. Here we show that a [2]catenane can act as a mechanical protecting group by diverting tensional forces away from a mechanically active functional group embedded in one of its rings. This property emerges from the mobility of the two rings of the catenane, which are able to rotate along each other until the tension equalizes over the entirety of the catenated framework. This approach provides a new way to control the mechanical activity of a mechanophore.
