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

Small and Neutral TcvO BAT, Bisaminoethanethiol (N2S2) Complexes for Developing New Brain Imaging Agents
TL;DR: It was demonstrated that technetium complexes containing gem-dimethyl substituents have higher lipophilicities, whereas those with an amide group possess greater stability, which enhances ligand-exchange reaction.

Intramolecular 4 + 3 Cycloadditions. Cycloaddition Reactions of Cyclic Alkoxyallylic and Oxyallylic Cations
TL;DR: The intramolecular 4 + 3 cycloaddition of oxyallylic and alkoxyallylic cations has been studied in this paper, and it has been shown that six-through eight-membered cations react differently and give increasingly larger amounts of cycloadduct derived from extended (exo) transition states.

TL;DR: 4-Phenoxyphenoxyethyl thiocyanate presents very good prospective not only as a lead drug but also as a potential chemotherapeutic agent as well as introducing a sulfur atom at the polar extreme for this family of compounds.

TL;DR: Protoplasts derived from developing soybean cotyledons were used to study substrate recognition by a sucrose transporting protein in plant membranes and Binding of phenyl-alpha-D-thioglucopyranosides shows that the glucosyl hydroxyls at positions 3, 4, and 6 are involved in substrate Recognition by the carrier protein.
