Abstract

Three new macrocyclic β‐dihydroagarofuran‐type sesquiterpene pyridine alkaloids, fortuneines A (1), B (2), and C (3), together with the four known alkaloids wilfornine E (4), aquifoliunine E‐I (5), euoverrine B (6), and euojaponine I (7), were isolated from the aerial parts of Euonymus fortunei. Their structures were elucidated by spectroscopic methods, including HR‐ESI‐MS, ^1^H‐ and ^13^C‐NMR, DEPT, ^1^H,^1^H‐COSY, HSQC, HMBC, and ROESY. This is the first isolation of the above sesquiterpene pyridine alkaloids from this plant, except for compound 6.
