Abstract:
(11) Potassium ferricyanide has previously been used to convert w'c-1,2-dicarboxylate groups to double bonds. See, for example, L. F. Fieser and M. J. Haddadln, J. Am. Chem. Soc., 86, 2392 (1964). The oxidative dldecarboxylation of 1,2-dlcarboxyllc acids is, of course, a well-known process. See Inter alia (a) C. A. Grob, M. Ohta, and A. Weiss, Helv. Chim. Acta, 41, 1911 (1958); and (b) E. N. Cain, R. Vukov, and S. Masamune, J. Chem. Soc. D, 98 (1969).read more

Peptidic phosphonylating agents as irreversible inhibitors of serine proteases and models of the tetrahedral intermediates.
TL;DR: A detailed kinetic analysis of the enzyme-inhibitor interactions was complicated by the susceptibility of the inhibitors to enzymatic degradation, and the configuration at phosphorus was found not to have a significant influence on the rate at which the inhibitors react with the peptidases.

Mutagenicity of chlorine‐substituted furanones and their inactivation by reaction with nucleophiles
TL;DR: The reported high mutagenic potency of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone against Salmonella typhimurium (TA100) was confirmed in the determined value of 6,300 net revertants/nmol as discussed by the authors.

TL;DR: The epicuticular and internal waxes of male and female houseflies were examined by capillary gas chromatography-mass spectrometry at closely timed intervals from emergence until day-6 of adulthood and Mathematical analysis indicated that the time shift between internal production and external accumulation in females is more than 24 h.

Alkyl Substituent Effects on Pipecolyl Amide Isomer Equilibrium: Efficient Methodology for Synthesizing Enantiopure 6-Alkylpipecolic Acids and Conformational Analysis of Their N-Acetyl N'-Methylamides.
TL;DR: The results from the previous examination of N-acetyl-5-tert-butylproline N'-methylamides showed that the consequences of the bulky 6-alkyl substituent on the acetamide geometry and isomerization barrier were less pronounced in the pipecolate series relative to the respective proline amides.

Rapid shifts in the chemical composition of aspen forests: an introduced herbivore as an agent of natural selection
Joseph K. Bailey,Joseph K. Bailey,Jennifer A. Schweitzer,Jennifer A. Schweitzer,Brian J. Rehill,Duncan J. Irschick,Thomas G. Whitham,Richard L. Lindroth +7 more
TL;DR: The results indicate that introduced herbivores can have rapid evolutionary consequences even on long lived native species, and are likely to have cascading impacts on the services ecosystems provide.
