Abstract Calarene was oxidized by Bacillus megaterium and Diplodiagossypina to give allylic calarenols and calarendiols in which either of the geminal methyl groups of the cyclopropane ring was hydroxylated. Globulol was hydroxylated faster and in higher yields than calarene by both strains. In the case of this compound, vicinal diols were formed and, again, either of the geminal methyl groups was

Both 7α-hydroxy- and
7α,15-dihydroxy-aromadendrane are efficiently hydroxylated
by Mucor plumbeus at C-14 with retention of the adjacent
cyclopropane ring.
