The study of the isomerization of trans-3-acetoxy-2-bromocyclooctene
<p>The isomerization of trans-3-acetoxy-2-bromocyclooctene (trans-1) to cis-3-acetoxy-2-bromocyclooctene (cis-1) was studied, trans-3- Methoxy-2-bromocyclooctene (trans-2) was used as a model compound for comparison. The rate of isomerization of both compounds increased tremendously with iodine …

Carbachol- and ACPD-Induced Phosphoinositide Responses in the Developing Rat Neocortex
Signal transduction via the phosphoinositide (PI) second messenger system has key roles in the development and plasticity of the neocortex. The present study localized PI responses to individual cortical layers in slices of developing rat somatosensory cortex. The acetylcholine agonist carbachol …

Metabolic Studies on 1-Cyclopropyl-4-phenyl-1,2,3,6-tetrahydropyridinyl Derivatives by HPLC and LC-ESI/MS
… presumably is processed by a single electron transfer (SET) pathway to generate a bioalkylating species. These results have prompted us to study how the cytochromes P450, the major liver drug metabolizing oxidases, interact with N-cyclopropyl analogs of MPTP. HPLC with diode array detection …

Radical anion rearrangements. aryl cyclopropyl ketyl anions
… as diagnostic probes for single electron transfer (SET) in organic chemical reactions. The implicit assumption in such studies is that the formation of rearranged product(s) can be ascribed to the intermediacy of a ketyl anion. Through a detailed examination of the decay of …

The Reaction Kinetics of Neutral Free Radicals and Radical Ions Studied by Laser Flash Photolysis
… This trend was observed in aryl ketones such as trans-1-benzoyl-3-phenyl cyclopropane. It is believed that the generation of a benzyl radical during the decay that facilitates the enhancement of the unimolecular decays. These unimolecular decays were also observed with the previously studied …
