Monoester substituted -hydroxy cyclopropenes on treatment with catalytic Bi(OTf)3 lead to [5,5]/[6,5] oxaspirocyclic lactones. This unified strategy relies on generation of transient donor-acceptor (D-A) cyclopropanes from -hydroxy cyclopropene precursors. This approach allows for the sequential addition of two nucleophiles in ‘one pot’ process for the synthesis of THP derivatives.

By utilizing the conjugated cyanamide group, lithium-ion migration is promoted, while significantly suppressing lithium dendrite growth. The assembled Li/Li symmetric cell maintains stable cycling for over 1100 hours. Impressively, ionic conductivity degradation is also significantly restrained when exposed to air with 10% humidity for 24 hours.
