title: An improved synthesis of [26-(2)H3]castasterone.
abstract: Commercially available epicastasterone has been employed as a starting material for the preparation of [26-(2)H3 ]castasterone. The chemical synthesis has been realized in 13 chemical steps and 4.6% total yield. The target compound is intended to be used as internal standard for the quantitative analysis of brassinosteroids.
