説明

<jats:p>Karrikin (KAR<jats:sub>1</jats:sub>), also named ‘karrikinolide’, was isolated in 2004 from smoke water and identified as a very potent germination stimulant as well as controlling early seedling development for a large variety of plant species. We reported herein an unprecedented and scalable synthesis of Karrikin (KAR<jats:sub>1</jats:sub>) based on an elegant and efficient 6‐<jats:italic>endo</jats:italic>‐dig cyclization. Moreover, we evaluated the effect of KAR<jats:sub>1</jats:sub> on corn seeds germination, we carried out additional studies on the uptake of this butenolide into corn seeds, and the main soil chemiodynamic properties (<jats:italic>i.e</jats:italic>., persistence and mobility) were calculated or estimated. Finally, we provided a rationalization of the experimental results by building a homology model of corn KAI2, using as template the X‐ray of the KAI2 protein from <jats:italic>Arabidopsis thaliana</jats:italic>.</jats:p>
