Non-peptide RGD surrogates which mimic a Gly-Asp beta-turn: Potent antagonists of platelet glycoprotein IIb-IIIa

Cyclic heptapeptide 1, which contains an Arg-Gly-Asp sequence, has good affinity for the platelet receptor GPIIb-IIIa and was chosen for study by 1H NMR techniques. The key RGD sequence of this molecule was found to reside in a conformationally defined type II’ Gly-Asp beta-turn, and this information was used in the design of simple non-peptide RGD mimics. Disubstituted isoquinolones, bearing an acidic side chain at position 2 and a basic side chain at position 6, were prepared and were found to have modest affinity for GPIIb-IIIa. Systematic modification of the basic residue contained in these molecules yielded compounds with high affinity for GPIIb-IIIa.

Synthesis and conformational analysis of alpha,alpha-difluoroalkyl heteroaryl ethers

We report the efficient synthesis of difluoroalkyl aryl ethers from the rearrangement of heteroaryl ketones and aldehydes, mediated by xenon difluoride and HF/pyridine in methylene chloride at room temperature. Computational analysis of difluoroalkylethers shows that there is potential to allow access to conformational space not accessible to the hydrogenated parent.

Catalytic 1,3-Difunctionalization via Oxidative C-C Bond Activation

Electronegative substituents arrayed in 1,3-relationships along saturated carbon frameworks can exert strong influence over molecular conformation due to dipole minimization effects. Simple and general methods for incorporation of such functional group relationships could thus provide a valuable tool for modulating molecular shape. Here, we describe a general strategy for the 1,3-oxidation of cyclopropanes using aryl iodine(I-III) catalysis, with emphasis on 1,3-difluorination reactions. These reactions make use of practical, commercially available reagents and can engage a variety of substituted cyclopropane substrates. Analysis of crystal and solution structures of several of the products reveal the consistent effect of 1,3-difluorides in dictating molecular conformation. The generality of the 1,3-oxidation strategy is demonstrated through the catalytic oxidative ring-opening of cyclopropanes for the synthesis of 1,3-fluoroacetoxylated products, 1,3-diols, 1,3-amino alcohols, and 1,3-diamines.

Conjugated dual hydrogen-bond mediating proton-transfer reaction in 3-hydroxyisoquinoline

Proton-transfer tautomerism mediated by the conjugated dual hydrogen-bonding (CDHB) effect in the ground state as well as in the excited state has been studied in 3-hydroxyisoquinoline (3HIQ). In cyclohexane, upon increasing concentration or adding guest molecules possessing the bifunctional hydrogen-bonding property, spectral and dynamic analyses indicate the existence of equilibria between various proton-transfer tautomers, including enol monomers, enol dimers (or 1:1 enol/guest complex), and keto/enol complexes (or 1:1 keto/ guest complexes). The equilibrium constants among each species have been determined, which can be qualitatively rationalized through an ab inito molecular orbital calculation. The results conclude that the CDHB formation and its strength play a key role to fine-tune the ground-state equilibria toward the keto form. Upon excitation the enol CDHB complexes undergo a rapid proton-transfer reaction (kpt a?? 5 A? 109 s-1), resulting in a unique keto emission. Surprisingly, however, drastically different excited-state relaxation dynamics between the keto dimer and keto/enol complex were observed. The result was tentatively rationalized by a deactivation mechanism induced by vibrations of low-frequency hydrogen-bonding modes associated with the CDHB strength.

A practical and mild chlorination of fused heterocyclic N-oxides

Fused azine N-oxides were selectively chlorinated at C2 in moderate to excellent yields, employing Vilsmeier reagent as both the activating agent and the nucleophilic chloride source. Remarkable features of the method include simple operation, mild reaction conditions, a wide substrate scope, and the use of only stoichiometric amount of POCl3. The potential extension of this method to a one-pot oxidation/chlorination sequence that obviates the need for isolation of the N-oxide intermediates is also validated.
