A tandem radical macrocyclisation-transannular cyclisation approach towards the taxanes

Separate treatment of the iodotrienedione 19 and the iododienynedione 38 with Bu3SnH-AIBN produces the corresponding taxane ring systems 25 (25-30%) and 56 (50-60%) respectively by way of tandem radical macrocyclisation-radical transannular cyc
