A halide salt, hydroperoxide and AcOH catalyst system was applied to the oxidation of secondary benzylic alcohols. This simple system can be applied to a variety of secondary benzylic alcohols and scaled up for gram-scale preparation. High secondary benzylic alcohol selectivity of the present method is demonstrated in hydroxyketone synthesis. Based on several experimental results, a catalytic cycle for our oxidation is proposed.

Starting from thienobenzopyran HTS hit 1, co-crystallization, molecular modeling and metabolic analysis were used to design potent and metabolically stable inhibitors of PI3-kinase. Compound 15 demonstrated PI3K pathway suppression in a mouse MCF7 xenogra

Intramolecular reductive deoxygenation of ethylenedioxy tethered symmetrical and unsymmetrical aromatic bis(carbonyl) ethers with the low-valent titanium (LVT) reagent (TiCl4-Zn-THF) yielded chromatographically separable E/Z-isomers of corresponding cyclic stilbenes which were further dealkylated to obtain geometrically pure hydroxystilbenes. The intramolecular McMurry coupling of the tethered bis(carbonyl) ethers with TiCl 3-Li-THF, on the other hand, directly provided both symmetrical and unsymmetrical phenanthrenes via in situ dealkoxylation of the phenol function. This is the first report of the synthesis of unsymmetrical phenanthrenes by the LVT route.
