Benzannulation of arynes with dimethylacetonedicarboxylates via an insertion-fragmentation-Dieckman-aromatization cascade: Expeditious entry to naphthoresorcinols and binaphthoresorcinols
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
