accessible, and robust immobilized bifunctional organocatalysts. There was no need to employ any tether to secure high enantio- and diastereoselectivities in various Michael addition reactions. The synthetically useful Michael adducts were obtained within reasonable reaction times with the advantage of easy product isolation and the possibility of automation by using a flow chemistry apparatus.
本文描述了高效、易于获取且稳健的固定化双功能有机催化剂的制备。在各种迈克尔加成反应中不需要使用任何系链来确保高对映选择性和非对映选择性。合成有用的迈克尔加合物是在合理的反应时间内获得的,优点是易于分离产物,并且可以通过使用流动化学装置实现自动化。
