Process for producing 3-cyanomethyl cyclopentanone derivatives

摘要

A process for producing 3-cyanomethyl cyclopentanone derivatives which are useful precursors of fragrant components in jasmine and analogous thereof such as methyl jasmonoate, methyl dihydrojasmonate, etc., is disclosed. In the process, the jasmonoates are produced starting from beta -dicarbonyl compounds and azides through several-step reactions.
