Stereocontrolled Domino Reactions

Domino reactions are classified according to the mechanism of the individual steps, which may be of the same or different type. The quality and importance of a domino reaction can be correlated to the number of bonds generated in such a process and the increase in complexity. The concept of domino sequences has allowed easily reaching high molecular complexity with very often excellent levels of stereocontrol with simple operational procedures, as well as advantages of savings in solvent, time, energy, and costs. The use of one-component, two-component, and multicomponent domino reactions in asymmetric synthesis is increasing constantly. Such single-step reactions allow the synthesis of a wide range of structurally diverse and complex chiral molecules from simple substrates in an economically favorable manner by avoiding the use of costly and time-consuming protection deprotection processes, as well as purification procedures of intermediates.
