Immobilization of antioxidants via ADMET polymerization for enhanced long-term stabilization of polyolefins

Novel macromolecular antioxidants with multiple hindered phenolic antioxidant moieties along a linear, unsaturated olefinic backbone are prepared and their antioxidative ability in polypropylene (PP) blends is investigated. Firstly, alpha,omega-diene monomers bearing one alcohol functionality are prepared from 10-undecenoic acid, sourced from the renewable resource castor oil, and are subsequently coupled to hindered phenolic antioxidants to prepare antioxidant bearing alpha,omega-diene monomers. The preparation of macromolecular antioxidants is then described, via ADMET polymerization of the hindered phenol bearing monomers. Upon blending with polypropylene, the resultant blends show excellent antioxidative stabilization in comparison to commercially available antioxidants and thus represent promising additives for the long-term stabilization of polyolefins in extreme environments, for example in the construction of solar water heating systems.

Synthetic methodology for the construction of structurally diverse cyclopropanes

Practical and efficient routes for the stereoselective conversion of homoallylic alchols to diastereomerically pure cis-, trans-1,2-disubstituted, and 1,2,3-trisubstituted cyclopropanes have been developed. The routes are highlighted by olefin metathesis strategies and the stabilization of an intermediate cyclopropylcarbinyl cation by the beta-silicon effect. The stereospecificity of the key cyclization step has been rationalized by transition-state models in which the important determinants include (i) a minimization of the steric interactions about the forming cyclopropane bond and (ii) an inversion of stereochemistry at the activated homoallylic alcohol position. The cyclopropane product chirality is ultimately controlled by the choice of homoallylic alcohol starting material. Through this method nonracemic, diasteromerically pure homoallylic alcohols can be converted in two steps to nonracemic, diasteromerically pure cyclopropane structural units. The scope and limitations of this versatile methodology have also been investigated.

Monofunctional metathesis polymers via sacrificial diblock copolymers

(Chemical Equation Presented) A small price to pay: The second block of a diblock copolymer is “sacrificed” in order to leave behind a monofunctionalized metathesis polymer with a hydroxy end group. By incorporation of a dioxepine unit into the copolymer, a breaking point is created between the block to be end-functionalized and the block to be sacrificed.

The first synthesis of substituted azepanes mimicking monosaccharides: a new class of potent glycosidase inhibitors.

The synthesis of the first examples of seven-membered ring iminoalditols, molecules displaying an extra hydroxymethyl substituent on their seven-membered ring compared to the previously reported polyhydroxylated azepanes, has been achieved from d-arabinose in 10 steps using RCM of a protected N-allyl-aminohexenitol as a key step. While the (2R,3R,4R)-2-hydroxymethyl-3,4-dihydroxy-azepane 10, a seven-membered ring analogue of fagomine, is a weak inhibitor of glycosidases, the (2R,3R,4R,5S,6S)-2-hydroxymethyl-3,4,5,6-tetrahydroxy-azepane 9 selectively inhibits green coffee bean alpha-galactosidase in the low micromolar range (Ki = 2.2 muM) despite a D-gluco relative configuration.

Nitro-substituted Hoveyda-Grubbs ruthenium carbenes: Enhancement of catalyst activity through electronic activation

The design, synthesis, stability, and catalytic activity of nitro-substituted Hoveyda-Grubbs metathesis catalysts are described. The highly active and stable meta- and para-substituted complexes are attractive from a practical point of view. These catalysts operate in very mild conditions and can be successfully applied in various types of metathesis [ring-closing metathesis, cross-metathesis (CM), and enyne metathesis]. Although the presence of a NO2 group leads to catalysts that are dramatically more active than both the second-generation Grubbs’s catalyst and the phosphine-free Hoveyda’s carbene, enhancement of reactivity is somewhat lower than that observed for a sterically activated Hoveyda-Grubbs catalyst. Attempts to combine two modes of activation, steric and electronic, result in severely decreasing a catalyst’s stability. The present findings illustrate that different Ru catalysts turned out to be optimal for different applications. Whereas phosphine-free carbenes are catalysts of choice for CM of various electron-deficient substrates, they exhibit lower reactivity in the formation of tetrasubstituted double bonds. This demonstrates that no single catalyst outperforms all others in all possible applications.

Total synthesis of (-)-microcarpalide, a novel microfilament disrupting metabolite

The stereoselective total synthesis of (-)-microcarpalide, a recently discovered 10-membered lactone of fungal origin displaying a remarkable disrupting action on actin microfilaments, was accomplished by using ring-closing metathesis (RCM) as the key step for the formation of the medium-sized ring. The diene ester required for the macrocyclization reaction was assembled via DCC-mediated esterification of two suitable partners, each bearing a terminal alkene group. The alcohol fragment was synthesized from n-bromohexane through a seven-step sequence entailing two consecutive stereoselective homologations of chiral boronic esters as strategic transformations for the sequential insertion of the two stereocentres with the final S absolute configuration, using (+)-pinanediol as the chiral director; final elaboration to the desired C11 framework envisaged treatment with an allyl Grignard reagent and oxidative cleavage of the boronic scaffold. In contrast, the acidic fragment was prepared in ten steps from D-tartaric acid, whose C4 backbone was elongated to the required C7 skeleton by means of two distinct Swern-Wittig oxidation-homologation sequences.
