Stereospecfic alkenes are present in several natural products as the method continues to be exploited to yield a series of complex substrates. Professor T.K.M Shing et al used the Corey-Winter olefination reaction to synthesize (+)-Boesenoxide (scheme 16). 600px|center|total synthesis example of corey winter olefination CBS-type enantioselective Diels–Alder reaction has been developed using a similar scaffold to the enantioselective CBS reduction. After the development of this reaction the CBS reagent proved to be a very versatile reagent for a series of several powerful synthetic transformations. The use of a chiral Lewis acid such as the CBS catalyst includes a broad range of unsaturated enones substrates.
