Cyclodextrin-Promoted Radical Cyclization of o-(2-Propenyloxy)- and o-(2-Propynyloxy)-benzenediazonium Ions

Article abstract of DOI:10.1246/cl.1991.337

Radical dediazoniation of o-(2-propenyloxy)- and o-(2-propynyloxy)benzenediazonium ions in the presence of β-cyclodextrin gives selectively dihydrobenzofurans under N2, while hydroxymethylated dihydrobenzofurans and 3-hydroxymethyl-benzofuran under air, respectively.
