Abstract:
Reported herein is a novel and sustainable electrochemical seleno-/tellurocyclization of propargyl carboxylic acids, affording a diverse range of valuable Se-/Te-incorporated unsaturated γ-lactones under ambient conditions. Preliminary mechanistic studies suggest that this transformation predominantly proceeds via a cationic pathway.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
