Reanalysis of the biotransformation of 4(20),11(12)-taxadiene derivatives by Absidia coerulea ATCC 10738a unravelled additional unprecedented rearrangement reactions. 5α,7β,9α,10β,13α-pentaacetoxy-4(20),11(12)-taxadiene (1) was converted to 10 new minor taxane derivatives in addition to the previously reported C-1, C-14-hydroxylations and C-15-hydroxylated abeo-taxane. In addition, 2-deacetoxytaxinine J (2) was successfully metabolized with the same fungi.Key words: natural products, terpenes and terpenoids, microorganism, oxygenation, rearrangement.
