Arylcarboxylation/Cyclization/Hydrogenation Cascade of Arylalkynes with Formate: Synthesis of Ester-Substituted Dioxodihydrodibenzothiazepine Derivatives.

A novel method has been developed for the arylcarboxylation/cyclization/hydrogenation cascade reaction of arylalkynes with cheap and readily available sodium formate (HCO2Na). This approach facilitates the efficient synthesis of ester-substituted dioxodihydrodibenzothiazepine derivatives in the absence of photocatalyst...
