Abstract
The synthesis of 2α,3α-dihydroxy-B-homo-7-oxa-cholestan-6-one (VI), 2β,3β-dihydroxy-B-homo-7-oxa-5α-cholestan-6-one (VIII) and 2α,3α-dihydroxy-B-homo-6-oxa-5α-cholestan-7-one (XI) is described. The activity of these brassinosteroids in the bean second internode bioassay is lower than the activity of 24-epibrassinolide (XXI).
