We describe an aerobic intramolecular dearomative coupling reaction of tethered phenols using a catalytic system consisting of a chromium-salen (Cr-salen) complex combined with a nitroxyl radical. This novel catalytic system enables formation of various spirocyclic dienone products including those unable to be accessed by previously reported methods efficiently under mild reaction conditions.

A series of 4-substituted phenoxypropanolamines was prepared and examined for β-adrenoceptor activity.Some of the compounds, especially the oxy>ethoxy>phenoxy>propanolamines (14, 15, and 24), showed potent β1-blo
