General allylic C-H alkylation with tertiary nucleophiles

A general method for intermolecular allylic C-H alkylation of terminal olefins with tertiary nucleophiles has been accomplished employing palladium(II)/bis(sulfoxide) catalysis. Allylic C-H alkylation furnishes products in good yields (avg. 64%) with excellent regio- and stereoselectivity (>20:1 linear:branched, >20:1 E:Z). For the first time, the olefin scope encompasses unactivated aliphatic olefins as well as activated aromatic/heteroaromatic olefins and 1,4-dienes. The ease of appending allyl moieties onto complex scaffolds is leveraged to enable this mild and selective allylic C-H alkylation to rapidly diversify phenolic natural products. The tertiary nucleophile scope is broad and includes latent functionality for further elaboration (e.g., aliphatic alcohols, α,β-unsaturated esters). The opportunities to effect synthetic streamlining with such general C-H reactivity are illustrated in an allylic C-H alkylation/Diels-Alder reaction cascade: a reactive diene is generated via intermolecular allylic C-H alkylation and approximated to a dienophile contained within the tertiary nucleophile to furnish a common tricyclic core found in the class I galbulimima alkaloids.

Chemistry of Novel Compounds with Multifunctional Carbon Structure. 5. Molecular Design of Versatile Building Blocks for Aliphatic Monofluoro Molecules by Manipulation of Multifunctional Carbon Structure

Three kinds of doubly functionalized monofluoromethylene fragments, 1-fluoro-1-nitro-1-(phenylsulfonyl)alkanes (10), 2-fluoro-2-(phenylsulfonyl)alkanoic esters (11), and 2-fluoro-2-nitroalkanoic esters (12), potentially versatile building blocks for the general synthesis of various aliphatic monofluoro molecules, were prepared from the corresponding difunctional compounds 1-3 by monoalkylation (R) and selective fluorinations.The interconversion or reductive removal of each functional group in 10-12 followed by the introduction of the second alkyl groups (R') at the fluorine-bearing carbon atom was examined.Compounds 12 proved to be useful and practical building blocks for conversions to the various monofluoroalkanes 20-26.

α-NITRO SULFONES. 2. CONVENIENT NEW SYNTHESIS AND SELECTED FUNCTIONAL GROUP TRANSFORMATIONS

(Phenylsulfonyl)nitromethane (1) is preferentially C-alkylated by benzylic halides and primary alkyl iodides, affording secondary α-nitro sulfone products. α-Nitro sulfones are also obtained from the corresponding C-alkylation of allylic acetates in the presence of catalytic tetrakis(triphenylphosphine)palladium.The palladium(0)-catalyzed reaction is stereospecific for geranyl and neryl acetates and is also regioselective.Desulfonation of α-nitro sulfones is readily accomplished by light-induced reduction with 1-benzyl-1,4-dihydronicotinamide (BNAH).Reduction of secondary α-nitro sulfones with 20percent aqueous titanium(III) chloride affords nitriles.Oxidation with alkaline permanganate affords carboxylic acids.
