Rapid, efficient and solvent-free synthesis of (un)symmetrical xanthenes catalyzed by recyclable sulfated polyborate

The present study describes a rapid, simple and straightforward approach to the synthesis of 1,8-dioxo-octahydroxanthenes, 14-phenyl-14H-dibenzo[a,j]xanthene and tetrahydrobenzoxanthene-11-ones under solvent-free conditions using sulfated polyborate as a

Ruthenium/Yb(OTf)3-cocatalyzed dehydrogenative synthesis of 14-substituted-14-H-dibenzo[a,j]xanthenes from β-naphthol and alcohols

By employing [P^O]2Cl2Ru/Yb(OTf)3 as a new and efficient catalyst system [P^O = 2-(diphenylphosphino)-2,4-dimethylpentan- 3-one], readily available, abundant alcohols were firstly employed for dehydrogenative synthesis of 14-substituted-14-H-dibenzo[a,j]xanthenes. Due to the inherent stability of alcohols compared to aldehydes, the presented synthetic protocol is adaptable to a broad substrate scope, there is no need for stringent protection in the whole preparation process, providing the potential to prepare products that are currently inaccessible or challenging to prepare using conventional methods. It is an important complement to the conventional synthetic methodologies. This journal is the Partner Organisations 2014.
