Construction of Benzothiophene-Fused 1,2,4-Triazocines via a Skeletal Editing Strategy and DFT Study on the Reaction Mechanism
{{output}}
A series of benzothiophene-fused 1,2,4-triazocines were successfully synthesized through a one-pot skeletal editing strategy. The synthesis commenced with a [4 + 3] cycloaddition reaction to afford a benzothiophene-fused 1,2,4-triazepane intermediate. Subseque... ...
