α-humulene synthase was investigated through isotopic labelling experiments for its stereochemical course regarding inversion or retention at C-1, the face selectivity at C-11, and the stereoselectivity of the final deprotonation. A new and convenient desymmetrisation strategy was developed to enable a full stereochemical analysis of the catalysed steps to the achiral α-humulene product from stereoselectively
