1-Alkoxycarbonyl-3-halogenoazetidin-2-ones as elastase (PPE) inhibitors

A series of 1-alkoxycarbonyl-3-halogenoazetidin-2-ones, designed as potential suicide inhibitors of serine proteases, has been synthesized and evaluated against porcine pancreatic elastase (PPE). All the compounds were transient inhibitors, their activity depending mainly on the nature of the halogen substituent: bromo- and iodo- derivatives are more active (Ki ?2-22 muM) than 3-chloroazetidinones (Ki ?20-150 muM). The lipophilicity of the N-1 substituent appeared to exert a slightly positive effect.

THE CONFORMATIONAL DEPENDENCE OF 6jPF,C IN SOME 4-FLUOROPHENYL DERIVATIVES OF METHANE, ETHENE, AND CYCLOHEXANE

The spin-spin coupling over six bonds between (19)F and (13)C nuclei on the sidechain in thirteen 4-fluorophenyl derivatives appears to be mediated by a ?-? mechanism.Its magnitude depends somewhat on the hybridization state of the carbon atom carrying the coupled nucleus, as well as on the electronegativity of substituents attached to this carbon atom.A consistent behaviour of this coupling is observed if its value is assumed to be proportional to sin2 theta, where theta is the angle by which the bond carrying the coupled carbon nucleus twists out of the ring plane.However, in the 4-fluorostyrene 6JpF,C is a ? electron coupling in the planar form, so that its magnitude decreases as the vinyl group twists out of the benzene plane.The ?-? contribution to this coupling is smaller than the ? component. 6JpF,C is used to assess the conformational preferences of a number of compounds, including 4-fluoro-alpha-methylstyrene, 4,4′-difluorodiphenylmethane, 1,1-dichloro-2,2-bis(4-fluorophenyl)ethane, and 1-(4-fluorophenyl)-N-methylcyclohexylamine.

Facile Access to Challenging ortho-Terphenyls via Merging Two Multi-Step Domino Reactions in One-Pot: A Joint Experimental/Theoretical Study

ortho-Terphenyls are of high interest for medicinal chemistry and materials science, but they are difficult to access. Herein, we demonstrate a straightforward and sustainable synthesis of highly functionalized ortho-terphenyls via joining an organocatalyzed two-step domino reaction (Knoevenagel/vinylogous Michael) with a DABCO/CuBr2 co-catalyzed three-step domino reaction (cyclization/tautomerization/aromatization) in a one-pot process. Overcoming necessity to isolate intermediate products leads to a reduction of energy, costs and waste for a broad scope of reactions. DFT calculations have been performed to investigate the thermodynamics of this one-pot process towards ortho-terphenyls and to study the reaction profile of the vinylogous Michael reaction under inclusion of solvent effects. Role of London dispersion forces in this transformation has been elucidated. It is shown that reaction kinetics and thermodynamics are slightly influenced by dispersion interactions. Furthermore, the addition of dispersion energy donors leads to small changes of reaction energies in some cases.

Development of an Imine Chaperone for Selective C-H Functionalization of Alcohols via Radical Relay

The design of a radical relay chaperone to promote selective C-H functionalizations is described. A saccharin-based imine was found to be uniquely suited to effect C-H amination of alcohols via an in situ generated hemiaminal. This radical chaperone facilitates the mild generation of an N-centered radical while also directing its regioselective H atom transfer (HAT) to the beta carbon of an alcohol. Upon beta C-H halogenation, aminocyclization, and reductive cleavage, an NH2 is formally added vicinal to an alcohol. The development, synthetic utility, and chemo-, regio-, and stereoselectivity of this imine chaperone-mediated C-H amination is presented herein.
