(PFTase). The key step in the synthesis of 1 involved the stereoselective coupling of vinyl triflate 8 with a lower order cyclopropyl cyanocuprate to afford the desired cyclopropyl ester 13. The sterically encumbered analog 3-desmethyl-3-tert-butylfarnesyl diphosphate (3-tbFPP, 7) was synthesized via a similar route. The use of the more reactive higherorder tert-butyl cyanocuprate led to lower yields of
