- DBU-Mediated Construction of 1,3,5-Trisubstituted Benzenes via Annulation of α,β-Unsaturated Carboxylic Acids and α-Cyano-β-methylenones
-
A DBU-mediated synthesis of 1,3,5-trisubstituted benzenes was developed via the [2 + 4] annulation of in situ activated α,β-unsaturated carboxylic acids and α-cyano-β-methylenones. The dual role of DBU as Br?nsted base and nucleophilic Lewis base is the key for the success of the reaction.

- TRIPHENYLENO-BENZOFURAN COMPOUND AND ORGANIC LIGHT EMITTING ELEMENT INCLUDING THE SAME
-
An organic light emitting element which realizes a high efficiency and long-life light emission is provided. An organic compound represented by the general formula [1] described in Claim 1 is provided. In the general formula [1], R1 to R3 are each independently selected from a hydrogen atom, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heterocyclic group. However, at least one of R1 to R3 represents the aryl group or the heterocyclic group. The aryl group represents a phenyl group, a naphthyl group, a phenanthrenyl group, a fluorenyl group, a triphenylenyl group, or a chrysenyl group. The heterocyclic group represents a dibenzofuranyl group or a dibenzothienyl group.
