Intramolecular trapping of allenylzincs by carbonyl groups
Allenylzinc formed via oxygen-promoted zinc/iodine exchange between propargyl iodides and diethylzinc can be trapped by intramolecular reaction with various electrophiles such as aldehydes, ketones, esters, carbamates, and imides. Potentially useful build
Radical dearomatization of benzene leading to phenanthridine and phenanthridinone derivatives related to (±)-pancratistatin
The synthesis of the phenanthridinone nucleus common to the Amaryllidaceae series of natural products is achieved by a sequence involving tributylstannane-mediated, benzeneselenol-catalyzed addition of ortho-nitrogen functionalized aryl radicals to benzen
