- Synthesis of heliannane skeletons. Facile preparation of (±)-heliannuol D
-
Heliannuol D is a natural product with a 7,10-heliannane skeleton, isolated from Helianthus annuus. It has been synthesized in eight steps, in good yield, using a new biomimetic method. Key steps were a Fries rearrangement, a Grignard reaction and, finall
