Bis- and tris-dihydroxyaryl compounds and their methylenedioxy analogs and pharmaceutically acceptable esters, their synthesis, pharmaceutical compositions containing them, and their use in the treatment of amyloid diseases, especially Aß amyloidosis, such as observed in Alzheimer's disease, IAPP amyloidosis, such as observed in type 2 diabetes, and synucleinophathies, such as observed in Parkinson's disease, and the manufacture of medicaments for such treatment.
Reductive coupling of benzoyl cyanide and carbonyl compounds by aqueous titanium(III) ions. A new convenient and selective access to the less stable mixed benzoins

The reactive species formed by the Ti(III) ion reduction of benzoyl cyanide (1) adds to the C-atom of carbonyl compounds 2 under simple experimental conditions. The intermediate 1,2-diols 3 are smoothly converted, without isolation, into the less thermodynamically stable mixed benzoins 4, which are not accessible by the classical benzoin condensation. The possible mechanisms involved in the reaction are discussed.
