were reacted with 2,2′-dihydroxybiphenyl (5) using p-toluene sulfonic acid monohydrate (PTSA) as a catalyst to obtain 6-α-aminodibenzo[d f][1,3,2]dioxaphosphepin 6-oxides (6) in good yield. It is a first report on the cyclizations of 4 with 5. An antimicrobial activity of numbers of 6 is evaluated. © 2007 Wiley Periodicals, Inc.
