ent -beyeran-19-oic acid), ent -16β-hydroxybeyeran-19-oic acid, and ent -16β-hydroxy-16α-methylbeyeran-19-oic acid by Gibberella fujikuroi has been shown to give ring A desoxybeyergibberellin analogues of GA 9 , GA 12 and GA 25 . The ent -16β-hydroxybeyeran-19-oic acid also gave some hydroxylated beyeranes and the 7β-hydroxybeyeranolide.
