Two diterpenecyclases, one from the social amoeba Dictyostelium discoideum and the other from the bacterium Streptomyces clavuligerus, with products containing a Z‐configured double bond between the original C2 and C3 of geranylgeranyl diphosphate, were extensively investigated for their mechanisms through isotopic labelling experiments. The participation of geranyllinalyl diphosphate, in analogy

Short practical syntheses for five deuterium-labeled derivatives of dimethylallyl diphosphate (DMAPP) useful for enzymological studies are reported. These include the preparation of the Cl-labeled derivatives (R)-[1-H-2]3-methylbut-2-enyl diphosphate ((R)-[1-H-2]1-OPP) and (S)-[1-H-2]3-methylbut-2-enyl diphosphate ((S)-[1-H-2]1-OPP), the C2-labeled derivative [2-H-2]3-methylbut-2-enyl diphosphate ([2-H-2]1-OPP), and the methyl-labeled derivatives (E)-[4,4,4-H-2(3)]3-methylbut-2-enyl diphosphate ((E)-[4,4,4-H-2(3)]1-OPP) and (Z)-[4,4,4-H-2(3)]3-methyl-but-2-enyl diphosphate ((Z)[4,4,4-H-2(3)]1-OPP).
