Abstract
Heliolactone is one of the earliest identified non-canonical strigolactones. Its concise synthesis was achieved by employing Knoevenagel-type condensation and semi-reduction of a malonate intermediate as the key steps. This synthesis was performed in a non-stereoselective manner, and thus a racemic and diastereomeric mixture of heliolactone was obtained. The developed synthetic route is fairly concise and straightforward.
Keywords:
Knoevenagel condensation; concise synthesis; germination stimulant; non-canonical strigolactone.
