Synthesis of (+/-)-brazilin using IBX.
[reaction: see text] A short synthesis of (+/-)-brazilin is reported. This synthesis uses several interesting and underutilized transformations including a regioselective dirhodium-catalyzed aryl C-H insertion, a regioselective IBX phenol --> o-quinone oxidation, a tautomerization of an o-quinone to a p-quinone methide, and an intramolecular aryl cyclization with a p-quinone methide.
متن کاملSynthesis of a Novel Siliconized Analog of Clofibrate (Silafibrate) and Comparison of their Anti-inflammatory Activities
Fibrates, as hypolipidemic drugs known as agonists of peroxisome proliferator-activated receptors, diminish inflammatory responses. Studies have shown that incorporation of a silicon atom into a drug structure improves its pharmacological potency, modifies its selectivity toward a given target, or changes its metabolic rate, in addition to increasing the lipophilicity of the compounds. A si...

متن کاملOASYS: a framework for analog circuit synthesis
We describe a hierarchical structure for a knowledge-based analog circuit synthesis tool. Analog circuit topologies are represented as a hierarchy of abstract functional blocks each with associated design knowledge. We also describe mechanisms to select from among alternate design styles, and to translate performance specifications from one level in the hierarchy to the next lower level. A prot...
