Реферат: Reduced derivatives of 2,3-seco-28-oxo-19 beta,28-epoxy-18 alpha-olean-2,3-dicarboxylic acid and its cyclic anhydride were prepared. Reduction of the starting 2,3-secodicarboxylic acid by NaBH(4)-I(2) produced the 2,3-seco-2,3-dihydroxy derivative. Reaction of the starting anhydride with LiAlH(4) gave the 2,3-seco-2,3,19 beta,28-tetrahydroxy derivative. Cyclization using acidic reagents of the 2,3-seco-2,3-hydroxy- and 2,3-seco-2,3,19 beta,28-tetrahydroxy derivatives gave the corresponding cyclic ethers containing an oxepane ring. The anhydride ring was reduced by NaBH(4) to the corresponding epsilon-lactone, the structure of which was confirmed by an x-ray crystal structure.
