Selective bromocyclization of 2-geranylphenols promoted by phosphite-urea cooperative catalysts

, : Selective bromocyclization of 2-geranylphenols promoted by phosphite-urea cooperative catalysts. Chirality 26(7): 356-360

Nucleophilic phosphite-urea cooperative catalysts are highly efficient for the bromonium-induced cyclization of 2-geranylphenols. Phosphite-N,N'-dimethylurea catalysts also show moderate activity, probably due to the steric effect of their bent conformation.
