FIELD: chemistry.
SUBSTANCE: described is a method of producing 7,8-dihydro-analogues of ecdysteroids via catalytic hydrogenation of ecdysteroids in methanol solution containing 1:6-fold excess Na metal in the presence of a Pd/C catalyst (1:1 to the weight of the substrate).
EFFECT: obtained 7,8-dihydro-analogues of ecdysteroids are structurally similar to castasterone type brassinosteroids - highly active phytohormones, plant growth and development stimulants.
