E=MCR2! The introduction of orthogonalfunctional groups in multicomponent reactions (MCRs) with unique solvent and functional‐group compatibility enables their combination with other multicomponent reactions in one pot. The resulting novel 5‐ and 6CRs and an unprecedented 8CR afford very complex products in up to 80 % yields (see picture), with up to nine new bond formations and eleven diversity points
E = MCR 2!具有独特溶剂和官能团相容性的多组分反应(MCR)中引入正交官能团,使其能够与其他多组分反应在一个罐中结合使用。由此产生的新颖的5CR和6CR以及前所未有的8CR提供了非常复杂的产品,产率高达80%(见图),在一个反应中最多可形成9个新的键形成和11个多样性点。

Diversity‐oriented synthesis: The multicomponentreaction of α‐isocyano amides, aldehydes or ketones, and amines affords N‐(cyanomethyl)amides, presenting the fourth class of products from this combination of reagents (see scheme). The scope of the reaction is very broad and various functional groups are tolerated. The outcome of the reaction can also be directed to the formation of 2H‐2‐imidazolines
面向多样性的合成:α-异氰基酰胺,醛或酮与胺的多组分反应提供N-(氰基甲基)酰胺,这是该试剂组合的第四类产品(请参阅方案)。反应的范围非常广泛,并且可以容忍各种官能团。反应的结果还可以通过Ag I催化直接形成2 H -2-咪唑啉。
