(2Z,6E)-farnesyl diphosphate
(S)-beta-bisabolene + diphosphate
-
The synthesis of (S)-beta-macrocarpene from (2E,6E)-farnesyl diphosphate proceeds in two steps. The first step is the cyclization to (S)-beta-bisabolene. The second step is the isomerization to (S)-beta-macrocarpene ((S)-beta-macrocarpene synthase). Product is identified by GC-MS
