The chemical reactivity of radical cations derived from N,O-ketene acetals has been examined and compared with the reactivity of radical cations derived from both ketene dithioacetals and enol ethers. Synthetically, the N,O-ketene acetal radical cations lead to more efficient cyclization reactions than either the ketene dithioacetal or enol ether derived radical cations. Cyclic voltammetry experiments using allylsilane trapping groups show that the efficiency of these cyclizations is not due to the N,O-ketene acetal radical cations being more reactive but rather more stable to decomposition. Finally, cyclizations using chiral oxizolidinones were examined.

A new bifunctional fluorescent label, BRos, was synthesised in order to monitor protein dynamics using fluorescence microscopy, and the photophysical properties were compared with those of bifunctionalised rhodamine, BRho. In a labelling experiment with a model peptide of troponin C, which regulates muscle contraction and relaxation, it was found that BRos was bound to the peptide through two linkages and provided a homogeneous compound, whereas BRho gave a pair of diastereomers having different physical properties in NMR and HPLC analyses.

Synthetic stitching with silicon: Geminal alkylation-hydroxylation of alkynyl carbonyl compounds

A new strategy for the synthesis of beta-carbonyl-substituted tertiary alcohols from alpha,beta-alkynyl ketones and esters has been demonstrated. A silicon tether is used to internally deliver an alkyl group, which, combined with a C-Si to C-O transformation, can regio- and diastereoselectively “stitch” together geminal C-C and C-O bonds at the beta-position of an electron-withdrawing group. Regioselective alkyne hydrosilylation by a trans addition process provides clean access to trisubstituted vinylsilanes. Subsequent one-pot fluoride-induced C-C bond formation and oxidation of the resulting tertiary silane, a type of silane not normally reactive to such conditions, affords the desired products. The utility of neighboring ketone and carboxylate groups in promoting the oxidation of these highly hindered tertiary alcohols, an observation that may affect synthetic design of routes depending on such oxidations, is demonstrated. Good diastereoselection (>10:1) is observed for substrates bearing gamma-alkoxy stereocenters. Copyright

E-factor minimized protocols for the polystyryl-BEMP catalyzed conjugate additions of various nucleophiles to alpha,beta-unsaturated carbonyl compounds

Efficient protocols for the addition of carbon-, sulphur- and nitrogen-nucleophiles to alpha,beta-unsaturated carbonyl compounds catalyzed by PS-BEMP have been reported. The adoption of solvent-free conditions (SolFC) was crucial for improving the efficiency of all the processes, while by using an organic reaction medium poor results were obtained. Addition reactions were performed by using equimolar amounts of reagents, and the products were isolated by simple filtration with the minimal amount of organic solvent. This approach allowed the E-factor, a measure of the waste of a reaction, to be minimized. Further waste minimization (95.7% compared to batch protocol) has been accomplished by defining a larger scale continuous-flow protocol operating under SolFC.

Nickel-Copper-Catalyzed C(sp2)- N Cross-Coupling of Cyclic and Bridged Amides: An Access to Cyclic Enamides and Alkenyl Vince Lactams

An efficient C(sp2)- N cross-coupling of styrenyl and vinyl halides with cyclic and bridged amides catalyzed by nickel acetonylacetonate [Ni(acac)2] and copper(I) iodide (CuI) in the absence of any ligand has been developed. The reaction conditions are optimized to give the maximum yield of products using cesium carbonate (Cs2CO3) (2.0 equiv.) in N-methyl-2-pyrrolidinone (NMP) at 110 C under argon in the presence of Ni(acac)2/CuI (10 mol% each). A series of alkenyl derivatives of Vince lactams (bridged amides) and cyclic amides are obtained by this procedure. Halogen-containing styrenyl bromides also underwent coupling with amides to provide the products. The coupling is highly chemoselective as during the reactions the halogens (Br, Cl, F) on the aromatic ring remained intact and these can be used for further functionalization to make these enamides more useful. Although the (E)-styrenyl halides produced the corresponding (E)-styrenyl enamides, reactions with (Z)-styrenyl halides produced 1,3-di-ynes instead of (Z)-styrenyl enamides. This may be explained by the possibility of E2 type elimination of (Z)-styrenyl halides in the presence of a strong base like cesium carbonate followed by homocoupling. This catalyst system works efficiently for the N-arylation too along with N-styrenylation and vinylation. The bridged as well as cyclic amides successfully coupled with substituted aryl halides to provide the corresponding products. In general, the reactions are clean and high yielding. The operations are very simple and the products are obtained pure by standard column chromatography. The reaction is compatible with variety of amides and alkenyl bromides. The roles of nickel acetonylacetonate and copper(I) iodide in this reaction have been established and a possible reaction pathway has been outlined. The significant feature of this protocol is the alkenylation of Vince lactams via C(sp2)- N cross-coupling, which has not been reported so far and these products may have much potential in the pharmaceutical industry.

Unusual aluminum hydride-mediated reduction of N-(gamma- or delta-oxoacyl)oxazolidinone

Reduction of N-(gamma-oxoacyl)oxazolidinone with a borohydride reagent, such as NaBH4 or LiBEt3H, resulted in formation of the corresponding lactone or lactol. In contrast, when an aluminum hydride reagent was used instead of a borohydride reagent, reduction of N-(gamma- or delta-oxoacyl)oxazolidinone proceeded unexpectedly to give not the corresponding lactone or lactol, but a tetrahydrofuran or tetrahydropyran derivative, respectively, containing an oxazolidino group.
