Abstract

NEW MATERIAL:[ 22R,23R ]-B-Homo-7-oxa-5α-cholestan-6-one derivative of formulaI.
EXAMPLE: [ 22R,23R ]-B-homo-7- oxa-5α-cholestan- 6-one-2α,3α,22,23-tetraol or 24-demethylbrassinolide.
USE: Plant growth accelerator.
PREPARATION: For example, 22,23-dehydrocholesterol of formula III is oxidized in the presence of N-methylmorpholine N-oxide to give[22R,23R]-22,23-dihydroxy-cholesterol of formula IV, which is made subsequently to react with p- toluenesulfonic acid and methanesulfonyl chloride to give the compound of formula V. The product is subjected to oxidation, desulfonation, oxidation and acylation to give a novel intermediate of formula IV,[22R,23R]-2α,3α-diacyloxy-5α-cholestan-6-one-22,23-diol 22,23-acetanilide. Finelly, the intermediate is oxidized and subjected to deprotection to give the compound of the example.
