Synthesis of 22S,23S-brassinosteroids based on stigmasterol
- 1. Institute of Bioorganic Chemistry, Minsk (USSR)
Description
The analogs of 29C-brassinosteroids based on stigmasterol, i.e., 22S,23S-homo-castasterone and 22S,23S-homobrassinolide, were synthesized. Electrophilic additions at the Δ22-bond, hydroxylation with osmium tetroxide, and epoxidation followed by conversion of the epoxide into the diol were used for the construction of the 22S,23S-diol grouping. The PMR spectra of 5% solutions in deuterochloroform were obtained on JNM-PS-100 and WM-360 instruments at 100 and 360 MHz respectively with TMS as internal standard
