Saturated Heterocycles as Chiral Auxiliaries

Although various enantioselective catalytic reactions are available for many important stereoselective transformations, diastereoselective auxiliary-controlled synthesis is still an important area of organic synthesis. Chiral heterocyclic auxiliaries are frequently used due to good availability and efficient chirality transfer via the rigid heterocyclic scaffold. The following chapter focuses on recent examples and gives a brief overview of the applications of heterocyclic auxiliaries in diastereoselective synthesis. Illustrative examples were chosen to spotlight the underlying principles.
