Article abstract of DOI:10.1016/0040-4039(95)01141-4

A 17-hydroxy-16β, 17-dihydrogibberellin, GA₈₂9, was first isolated from a fungus, Phaeosphaeria sp. L487, and was synthesized from naturally abundant GA₄1 in a highly stereocontrolled manner whose essential step was inversion of C(16) configuration of readily accessible 16β-formyl intermediate 5 to more stable 16α-epimer 6 by base treatment.
