Cyclisation meaning
Webcyclization. noun Chemistry. the formation of a ring or rings. WebThe Nazarov Cyclization is a rare example of a Lewis acid-catalyzed 4-π conrotatory electrocyclic reaction. Asymmetric induction could be achieved if a chiral Lewis acid were able to control the direction of the conrotatory closure. However, only a few such reactions have been reported.
