Aryne insertions into 1,3,5-tricarbonyl bearing dimethylacetonedicarboxylate (DMAD) proceeds through a 4-step cascade process to eventuate in a versatile one pot synthesis of functionally embellished naphthoresorcinols. Functional group amplifications and
Transition-Metal-Free Benzannulation of Tricarbonyl Derivatives with Arynes: Access to 1,3-Dinaphthol Precursors for the Synthesis of Rhodamine Dye Analogues

Herein, we report a transition-metal-free annulation reaction of benzynes and 1,3-oxopentanedioate for the synthesis of highly functionalized naphthalene derivatives for the first time. Additionally, the representative naphthalene derivatives have been successfully transformed into the new series of rhodamine dye analogues.
