Preparation of partially protected brassinosteroids is achieved through the reaction of the source material (24-epicastasterone and 24-epibrassinolide) with diol-specific reagents (2,2-dimethoxypropane and methylboronic acid). The obtained products were shown to be useful synthetic intermediates for further preparation of minor representatives
