Isolation, Total Synthesis and Anti-Diabetic Activity of Filiforidine from <i>Cassytha filiformis</i>.

ABSTRACT: Cassytha filiformis is a folkloric herbal medicine used to treat type 2 diabetes mellitus (T2DM). In this study, an oxidized aporphine alkaloid, designated as Filiforidine (3,10,11-trimethoxy-1,2-methylenedioxy-7-oxoaporphine), was isolated from C. filiformis, and its structure was elucidated through comprehensive spectroscopic analysis. Owing to its novel structure and significant glucose consumption activity, the total synthesis of Filiforidine was achieved for the first time. The key steps featured an electrophilic addition reaction, involving the reduction of a nitro group to an amino group with lithium tetrahydroaluminum, and a copper bromide-catalyzed oxidative aromatization reaction as well as a photocyclization reaction. Several experimental steps were optimized. Furt
