1,3-Dibromo 5,5-dimethylhydantoin (DBH): A novel and efficient catalyst for the synthesis of 14-aryl-14H-dibenzo[a, j] xanthenes under solvent-free conditions
An atom-efficient and environment-friendly approach for the synthesis of aryl-14 H -dibenzo[ a,j ]xanthenes ( 3a–o ) via the one-pot reaction of β-naphthol and aryl aldehydes ( 1 ) catalyzed by DBH has been developed. The present approach offers several advantages such as reduced reaction times, mod...

Summary: | An atom-efficient and environment-friendly approach for the synthesis of aryl-14
H
-dibenzo[
a,j
]xanthenes (
3a–o
) via the one-pot reaction of β-naphthol and aryl aldehydes (
1
) catalyzed by DBH has been developed. The present approach offers several advantages such as reduced reaction times, moderate temperature, higher yields, solvent free, eco-friendly reaction condition, easy purification and economic availability of the catalyst. |
