Azaanthracenes via Inverse Electron-Demand Diels–Alder Reaction(2016) Tetrahedron Lett. 2016 , 57, 5639–5643.0040-4039https://kr.cup.edu.in/handle/32116/552Significance: Azaanthracenes are important fluo- Comment: The benzyne derivative is generated in rophores that are used in a number of applications such as metal or pH sensors. In this report the authors describe a new synthesis of this type of structure via an inverse electron-demand aza- Diels–Alder reaction between a benzyne derivative and an electron-deficient triazine. situ from the diazotization of 2-amino-3-naphthoic acid. It was found that the cyano activating group at the 5-position of the triazine is crucial for the reaction to take place because it offers a smaller energy difference between the cycloaddition HOMO and LUMO.enaza-Diels–Alder reactiontriazinesfluorophoresArticle
