Domino-Redox Reaction Induced by a Conformational Change Based on Dithiin Bisquinodimethane Skeleton
摘要
Domino reactions are intramolecular reactions in which a single event triggers the conversion of a starting material to a product, which then provides a substrate for the next reaction until a stable final product is obtained (Fig. 4.1a) (Tietze in Chem. Rev. 96:115–136, 1996; L. F. Tietze, Domino Reactions: Concepts for Efficient Organic Synthesis., Wiley (2014);Nicolaou et al. in Chem. Commun. 3:551–564, 2003;Nicolaou et al. in Angew. Chem. Int.

They have contributed greatly to green chemistry such as by improving the reaction efficiency (atom economy) and simplifying the workup process, thanks to the generation of multiple bonds in a single step.
