A Novel Route to Substituted Cyclopent-2-en-1-one; Application to the Synthesis of cis-Jasmone and Dihydrojasmone
Mathew, Jacob,Alink, Ben
, p. 684 - 686 (2007/10/02)
A short and efficient synthesis of cis-jasmone and dihydrojasmone has been achieved by the reaction of sulphur-stabilized carbanions with ethyl 2-chloro-2,3-dialkylbut-3-enoates.
