title: Synthesis and biological activity of furostanic analogues of brassinosteroids bearing the 5alpha-hydroxy-6-oxo moiety.
abstract: Two furostanic analogues of brassinosteroids bearing the 5alpha-hydroxy-6-oxo moiety were synthesized and their biological activity studied using the bean second internode elongation test. One of the compounds produced significant stimulation at doses of 2.5 and 5ng/plant.
