Epoxyanthracene Derivatives and Dicarbonylation on Benzene Ring via Hexadehydro-Diels-Alder (HDDA) Derived Benzynes with Oxazoles

A capture reaction of hexadehydro-Diels-Alder (HDDA) derived benzyne with various substituted oxazoles is reported. With methyl, hydrogen, or phenyl as the substituent at 2-position of oxazole, tetraynes afforded epoxyanthracene derivatives or underwent dicarbonylation on benzene ring. The reaction does not require any catalyst or additive. The mechanism behind the reaction was investigated. The obtained polycyclic product structure has potential application value in optoelectronic materials. The availability of dicarbonylated arene implies the uniqueness of HDDA benzyne reaction compared with traditional benzyne.

Synthesis method of benzoxazolidine derivative

The invention relates to a synthesis method of a benzoxazolidine derivative, the tetrayne compound and the 5, 5-dimethyl-1-pyrroline-N-oxide are subjected to a heating condensation reflux reaction, the reaction conditions are mild, and the synthesis method is simple. Compared with the prior art, the invention provides a brand-new synthesis method of the benzoxazolidine derivative, and a series of new benzoxazolidine derivatives are generated. The synthesized benzoxazolidine derivative has the advantages of high atom economy, more complex and diverse structure and certain application prospect.

Access to Benzoxazepines and Fully Substituted Indoles via HDDA Coupling

The HDDA-derived benzyne intermediate was captured by oxazolines based on the addition reaction of benzyne to the Ca?N double bond. Benzoxazepine derivatives, fused benzoxazepine derivatives, and fully substituted indoles are synthesized in one step. The reaction does not require any catalyst or additives. Possible reaction mechanisms are presented.
