ABSTRACT:
A four-step process for producing (-)-dihydrochrysanthemolactone from 2-caren-4-one is disclosed. The four steps in order are methylating 2-caren-4-one, oxidizing, methylating the tautomeric mixture resulting from the oxidation, and finally lactonizing the single hydroxy acid resulting from the second methylation. Additionally, three novel intermediate compounds that are produced by the steps in the process are disclosed.
