Novel and Efficient Synthesis of Rotenoids via Intramolecular Radical Arylation

Treatment of the iodoarylchromenes 22 with palladium acetate gave the tetracyclic compounds 23 via a formal but stereochemically disallowed Heck reaction; a crystalline intermediate palladium species 25 (X-ray analysis) was isolated.The method was employe

Rotenoid Synthesis via Radical Cyclisation

The (+/-)-6aα, 12aα, 12α-chromanochromanol acetate (11; R=Ac), representing the core structure of the insecticidal rotenoid alcohol (2), has been synthesised in six steps from the chromone (4); the cis,cis-stereochemistry is obtained in an intramolecular 6-exo aryl radical addition.
