Question

what is the example of the multi component Reaction​

Answer 1

Answer:

Multicomponent Reactions (MCRs) are convergent reactions, in which three or more starting materials react to form a product, where basically all or most of the atoms contribute to the newly formed product. In an MCR, a product is assembled according to a cascade of elementary chemical reactions. Thus, there is a network of reaction equilibria, which all finally flow into an irreversible step yielding the product. The challenge is to conduct an MCR in such a way that the network of pre-equilibrated reactions channel into the main product and do not yield side products. The result is clearly dependent on the reaction conditions: solvent, temperature, catalyst, concentration, the kind of starting materials and functional groups. Such considerations are of particular importance in connection with the design and discovery of novel MCRs.

Answer 2

The first reported multicomponent reaction was Strecker's synthesis [113] of α-amino cyanides (166) in 1850 (Scheme 3.24). Scheme 3.24. Strecker synthesis of α-amino cyanides. Another example of multicomponent reactions is Hantzsch's pyrrole synthesis [114].
