The first synthesis of the 5,5-difluoro-(12R)- and -(12S)-leukotrienes B3 is reported which uses a flexible and convergent strategy. The key steps involve a Sonogashira coupling between the bromodienone 4 and the propargylic difluoride 5; this is followed by a CBS type reduction to establish the (12R) or (12S) stereocenters. A final semihydrogenation, under controlled conditions, affords the required E,E,Z trienic system.
