• ]. Their interconversion could be a non-enzymatic process catalysed by weak acids, e.g., during work-up, but the acid-catalysed conversion of 4a is known to give a mixture of α-, β-, and γ-eudesmol [57], but not 7-epi-α-eudesmol, which demonstrates the participation of the enzyme to fix 4a in the correct
