Regioselective lithiation of benzyl imidazole: Synthesis and evaluation of new organocatalysts for trans-diol functionalization.

Benzyl imidazole was successfully lithiated using n-BuLi at ?78 °C and verified by deuterium incorporation. The chemical reaction of the lithiated benzimidazole was explored with a series of different electrophiles. This approach was utilized to synthesiz

Alcohol cross-coupling for the kinetic resolution of diols via oxidative esterification

We present an organocatalytic C-O-bond cross-coupling strategy to kinetically resolve racemic diols with aromatic and aliphatic alcohols, yielding enantioenriched esters. This one-pot protocol utilizes an oligopeptide multicatalyst, m-CPBA as the oxidant, and N,N-diisopropylcarbodiimide as the activating agent. Racemic acyclic diols as well as trans-cycloalkane-1,2-diols were kinetically resolved, achieving high selectivities and good yields for the products and recovered diols.
