allows regio- and stereocontrolled access to a variety of functionalised and substituted seven-membered rings. The substitution array can be diastereoselectively modulated by appropriate choice of the reaction partners, and the reaction allows the control of up to five newly created stereocentres and a complete chiral induction in the case of an optically active ketone precursor. The high level of
MARDi级联是最近发明的涉及1,3-二羰基衍生物的三组分迈克尔引发的缩合反应。它允许区域控制和立体声控制访问各种功能化和取代的七元环。取代阵列可通过的反应伙伴适当选择非对映选择性调制,并将该反应允许多达五个新创建的立体中心和一个完整的手性诱导中的光学活性前体酮的情况下的控制。观察到的非对映选择性的高水平归因于反应的总热力学控制。
