The site-selective functionalization of unactivated allylic C–H bonds via direct deprotonation using KTMP is described. The conversion of amorphadiene to artemisinic alcoholvia a simple, highly regioselective deprotonation over 4 other possible allylic sites is shown with further extrapolation to the first large-scale telescoped chemical synthesis of artemisinic acid from amorphadiene. Finally, application
