Stabilization of ketone and aldehyde enols by formation of hydrogen bonds to phosphazene enolates and their aldol products

Solution properties of enolates generated using the phosphazene (Schwesinger) base P4-tBu were investigated by NMR spectroscopy. With a full equivalent of base the benzyl ketones 1a and 1b, the acetophenone 2, the arylacetaldehyde 1c, and the methyl arylacetate 1d formed the expected “naked” (P4H+) enolates 3 and 7. However, at a half-equivalent of base the ketones 1a and 1b as well as the aldehyde 1c formed solutions of stable hydrogen-bonded dimeric (enol-enolate) structures (4). The acetophenone 2, on the other hand, forms only traces of the H-bonded dimer 8 during deprotonation of 2. The thermodynamic product was the isomeric self-aldol condensation product 12. The mechanism of this condensation was elucidated by low temperature rapid-injection (RI) NMR spectroscopy. Solutions of 8 stable enough for NMR characterization could be transiently generated by semiprotonation of the enolate 7 with HCl·OEt2 at -130 C using RINMR. The ester enolate 1d gave no trace of 4d even on a time scale as short as a few seconds at -130 C either during the semideprotonation of 1d, or during semiprotonation of the enolate 3d. Long-lived solutions of the enols derived from 1a, 1b, 1c, and 2 (but not 1d) could be produced by full protonation of the phosphazene enolates with HCl·OEt2 at low temperature. Copyright

Novel Hypoxia-Inducible Factor 1alpha (HIF-1alpha) Inhibitors for Angiogenesis-Related Ocular Diseases: Discovery of a Novel Scaffold via Ring-Truncation Strategy

Ocular diseases featuring pathologic neovascularization are the leading cause of blindness, and anti-VEGF agents have been conventionally used to treat these diseases. Recently, regulating factors upstream of VEGF, such as HIF-1alpha, have emerged as a desirable therapeutic approach because the use of anti-VEGF agents is currently being reconsidered due to the VEGF action as a trophic factor. Here, we report a novel scaffold discovered through the complete structure-activity relationship of ring-truncated deguelin analogs in HIF-1alpha inhibition. Interestingly, analog 6i possessing a 2-fluorobenzene moiety instead of a dimethoxybenzene moiety exhibited excellent HIF-1alpha inhibitory activity, with an IC50 value of 100 nM. In particular, the further ring-truncated analog 34f, which showed enhanced HIF-1alpha inhibitory activity compared to analog 2 previously reported by us, inhibited in vitro angiogenesis and effectively suppressed hypoxia-mediated retinal neovascularization. Importantly, the heteroatom-substituted benzene ring as a key structural feature of analog 34f was identified as a novel scaffold for HIF-1alpha inhibitors that can be used in lieu of a chromene ring.

Photochemical Transformation of O-(beta-Arylethyl) Arylimidates into 2,4-Diaryl-5-iodoxazoles with 1,3-Diiodo-5,5-dimethylhydantoin

Treatment of O-(beta-arylethyl) arylimidates with 1,3-diiodo-5,5-dimethylhydantoin (DIH) under irradiation with a tungsten lamp in 1,2-dichloroethane gave the corresponding 2,4-diaryl-5-iodoxazoles and 2,4-diaryloxazoles in good to moderate yields, respectively, depending on the aryl group. It was proposed that the reactions proceeded through the formation of N-iodoimidates by the reaction of O-(beta-arylethyl) arylimidates with DIH, followed by the formation of iminyl radicals via homolytic N?I bond cleavage, the 1,5-H shift by the iminyl radicals, the C?I bond formation of the formed carbon-centered radicals with iodine, the nucleophilic cyclization by the imino groups to form 2,4-diaryloxazolines, the oxidation of the formed 2,4-diaryloxazolines to 2,4-diaryloxazoles, and the iodination of the formed 2,4-diaryloxazoles to 2,4-diaryl-5-iodoxazoles with DIH.

Insecticidal heterolignans-Tubuline polymerization inhibitors with activity against chewing pests

Starting from natural product podophyllotoxin 1 substituted heterolignans were identified with promising insecticidal in vivo activity. The impact of substitution in each segment of the core structure was investigated in a detailed SAR study, and variation of substituents in both aromatic moieties afforded derivatives 5 and 43 with broad insecticidal activity against lepidopteran and coleopteran species. In vitro measurements supported by modeling studies indicate that heterolignans 3-134 act as tubuline polymerization inhibitors interacting with the colchicine-binding site. Insect specific structure-activity effects were observed showing that the insecticidal SAR described herein differs from reported cytotoxicity studies.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzodioxans, you can also check out more blogs about22013-33-8

Cycloalkylation of C(sp3)-H Bond with Neighboring Carboxylic Acid as Traceless Activating Group

Selective functionalization of inert C(sp3)-H bond is one of cutting-edge challenges in chemical synthesis. A novel strategy for selective C(sp3)-H bond cycloalkylation is developed with neighboring carboxylic acid as a traceless activating group. Primary and secondary alkyl carboxylic acids undergo decarboxylation/alpha-C(sp3)-H cleavage/cycloalkylation to give the five-membered cyclization products, while tertiary acids undergo decarboxylation/beta-C(sp3)-H cleavage/cycloalkylation to generate the six-membered cyclization products.
