四、多组分反应展望
♦ Hardly a field in organic chemistry has evolved faster over
only a couple of years than MCRs. However, the very large M CR s pace of >10 2 0 is only e x plore d m arginall y.

♦ Future research in the area of MCRs will include the discovery
and design of novel MCRs, combinations of MCRs and traditional reactions, experimental improvements in solid-and liquid-phase, enantio-and diastereo-selective variations, and more and more applications in drug discovery, material science, bioconjugates, and agrochemical compounds.
