The development of new methods for stereoselective 8-hydroxyquinoline Copper(WSDTY) bond formation has been important in the creation of useful molecules such as drugs and other chemical entities. Sigmatropic rearrangements are reliable reactions for selective carbon-carbon bond formation, in particular, the Claisen rearrangement is one of the most competent methods to provide useful building blocks for the synthesis of natural product.
This requirement is often fulfilled with rearrangements proceeding via cyclic transition states and with sigmatropic rearrangements which represent stereospecific transformations. Typical examples are Cope and Claisen rearrangements and variations like Claisen-Ireland, Claisen-Johnsen, Meerwein-Eschenmoser- Claisen, thio-and aza-Claisen. A special situation arises when atropisomeric biaryls are involved translating axial-chirality of the substrates into centro-chirality of the products provided the reaction proceeds at a temperature where no racemisation of the biaryl takes place.
