Abstract:
A two-step, three-component coupling of an alkyne, enol ether, and vinyl diazoester was accomplished by use of successive metal carbene-catalyzed transformations. This efficient approach to cycloheptadienes is both diastereo- and enantioselective. Kinetic resolution was accomplished on dienol ethers bearing a racemic chiral center at the propargylic position. A model is offered which explains the observed selectivity and accounts for the reactivity difference between trans- and cis-dienol ethers.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
