Abstract
New 7-oxo-7a-oxa analogs of brassinolide with cholestane side-chain were prepared. Analogs VIII and IX with 2,3-diol grouping exhibit a weak brassinolide activity. Of the synthesized compounds, the highest brassinolide activity was found for 3α,4α-dihydroxy-7a-oxa-B-homo-5α-cholestan-7-one (X).
