Their plant-growthpromoting activity was discovered in 1966 by Katsumi, and they were shown to be the intermediates in gibberellin biosynthesis. Quite independently from gibberellin research, stevioside was known since 1931 as a sweet glycoside from Stevia rebaudiana, a plant of Compositae.

In the course of this work, both C and D could be provided by degradation of commercially available gibberellin A3 . The relay synthesis of gibberellin A4 was completed in December 1967 just before Professor Yabuta’s 80th birthday.
