| 摘要 |
The invention relates to a method for producing cis-cyclopent-4-ene-1,3-diol and cis-cyclopent-4-ene-1,3-dialkanoates by selective cis-1,2-reduction of 4-hydroxycyclopent-2-enone by means of a hydroboron, in the presence of substoichiometric quantities of a trivalent rare earth metal compound, to form cyclopent-4-ene-1,3-diol which can then be optionally reacted with an acylation agent to form cis-cyclopent-4-ene-1,3-dialkanoates, in order to simplify the reprocessing and without intermediate isolation. |
