Abstract
Two new conformationally-restricted chiral bicyclic thiazolium salts h ave been synthesized by a concise, high-yielding route. These salts ar e effective catalysts for the benzoin condensation, affording benzoin in 20-30% yield, with a similar range of enantiomeric excesses. (C) 19 98 Elsevier Science Ltd.
