Author is Bernauer, Josef; Wu, Guojiao; Jacobi von Wangelin, Axel.

An iron-catalyzed allylation of organomagnesium reagents (alkyl, aryl) with simple allyl acetates proceeds under mild conditions (Fe(OAc)2 or Fe(acac)2, Et2O, r.t.) to furnish various alkene and styrene derivatives Mechanistic studies indicate the operation of a homotopic catalyst. The sequential combination of such iron-catalyzed allylation with an iron-catalyzed hydrogenation results in overall C(sp3)-C(sp3)-bond formation that constitutes an attractive alternative to challenging direct cross-coupling protocols with alkyl halides.

Author is Tillotson, John P.; Bogdanov, Georgii; Jucov, Evgheni V.; Khrustalev, Victor N.; Rigin, Sergei; Hales, Joel M.; Perry, Joseph W.; Timofeeva, Tatiana V..

Structural and spectroscopic characteristics of merocyanine dyes are important because of their potential applications in optoelectronics and sensors. Herein we report synthesis, X-ray diffraction characterization of crystal structure, spectroscopic and NMR studies of four merocyanine dyes which, according to their strong donor-acceptor structure, exhibit a second order polarizability (β). Crystallog. studies demonstrated an almost planar structure of all mols. and indicated the occurrence of conformational changes in π-conjugated bridge between donor and acceptor. For three homologues similar packing modes, defined mostly by week C-H···N interactions, were found in crystals. Bond length alternation (BLA) values have been evaluated using crystallog. and NMR data and have shown a correlation to their nonlinear optical activity. Second order polarizabilities for all compounds were measured using hyper Rayleigh scattering (HRS) in solution It was found that the merocyanines studied exhibit very large second order polarizabilities (up to 4.1 10-27 esu), making them potentially useful for materials for second harmonic generation (SHG). Unfortunately, they do not demonstrate acentric packing of chromophores, which is required for SHG in the crystalline state, but may show promise for other applications such as poled polymer blends or for SHG sensing in biol. environments.

We report the first total synthesis of the polyunsaturated fatty acid 7-hydroxydocosahexaenoic acid (7-HDHA) in racemic form and the enantioselective synthesis of 7-(S)-HDHA. Both syntheses follow a convergent approach that unites the C1-C9 and C10-C22 fragments using Sonogashira coupling and Boland reduction as key steps. These syntheses enabled the unambiguous characterization of this natural product for the first time and helped establish 7(S)-HDHA as a possible endogenous ligand for peroxisome proliferator-activated receptor alpha.
