The tetrabutylammonium-accelerated Norrish-Yang cyclization of 2-ethoxycarbonylmethyloxy- and 2-cyanomethyloxyacetophenones afforded trans -dihydrobenzofuranols in good stereoselectivities through cation-蟺 interactions between the ammonium and the carbonyl and cyano groups. Furthermore, a new type of ...
