title: Rhodium-catalyzed xanthone formation from 2-aryloxybenzaldehydes via cross-dehydrogenative coupling (CDC).
abstract: A concise and straightforward strategy to construct a xanthone skeleton via an intramolecular cross-dehydrogenative coupling (CDC) of 2-aryloxybenzaldehydes has been developed. The reaction proceeded smoothly without any need of preactivation of the aldehyde group. It can tolerate various functional groups and provides an applicable protocol to construct a wide range of xanthone derivatives.
