N-Heteropolycyclic Compounds from the Formal Intramolecular (4 + 1)-Cycloaddition of Chromium Aminocarbenes
摘要:
Chromium aminocarbenes tethered to dienes of all three electronic natures undergo an efficient intramolecular (4 + 1)-cycloaddition to give N-heteropolycyclic compounds. Ligands on chromium had a profound effect on the course of the reaction.
