Catalysis in Asymmetric Synthesis
There areseveral reviews available detailing the Sharpless asymmetric
epoxidation reaction.1,2 The first reports from the Sharpless group described the
stoichiometric use of the 'catalyst',3 however, the truly catalytic variant of the
reaction was ...

Connections Mechanisms of Asymmetric Epoxidation Reactions The epoxide
functional group is often an intermediate in organic synthesis sequences
because it can be readily opened by a variety of nucleophiles, leading to
complex ...
Eric V. Anslyn, Dennis A. Dougherty, 2006
Much of the experimental success of asymmetric epoxidation lies in exercising
proper control of equation (5).2 Both Ti(OR)4 and [Ti(tartrate)(OR)2] are active
epoxidation catalysts and since the former is achiral, any contribution by that
species ...

Name Reactions in Heterocyclic Chemistry
Initial studies on the Jacobson-Katsuki epoxidation reaction identified conjugated
cyclic and acyclic cis-disubstituted olefins as the class of olefins best suited for
the epoxidation reaction.“ Indeed a large variety of cis-disubstituted olefins have
...
