Abstract

Prezenta inventie se refera la un procedeu de obtinere a unor derivati de 28-metilbrasinolid cu formula generala I: (vezi formula) în care Z reprezinta (vezi formula) unul sau doi dintre radicalii R1, R2, R3 sunt independent unul de altul acetoxi metil-sau etilcetoxi, etoxiacetoxi, valeriloxi, butiriloxi, hexanoiloxi sau hepnanoiloxi, celalalt sau ceilalti doi radicali fiind hidrogen, caracterizat prin aceea ca, un mol dintr-un compus cu formula generala II: (vezi formula) în care Z are seminificatia de mai sus, se trateaza cu unul sau doi moli de anhidrida a unui acid carboxilic ales dintre acid acetic, metil-etil-sau etoxiacetic, valerianic, butiric, hexanoic sau heptanoic la temperatura de -5 degree C....0 degree C, în mediu de piridina.
