Disclosed herein are compounds and methods for promoting plant growth. Formulations containing one or more disclosed compounds or salts thereof, and one or more excipients are disclosed. The formulation adjuvant can be a solid carrier, a liquid carrier, or a surface-active agent. Methods for promoting plant growth typically includes applying one or more formulations to a plant, a plant part, or a growing site of plant. The plant can be a cereal, grain, or vegetable plant. The plant part can be seed or seedling of a plant. The growing site of plant can be soil before, during, or after the plant is planted or a growing medium. In some embodiments, the one or more compounds or salts thereof in the one or more formulations are in an effective amount to decrease biosynthesis and release of strigolactone plant hormones from the plant.

Provided herein are methods for preparing ketone-containing organic molecules. The methods are based on novel iron/copper-mediated (“Fe/Cu-mediated”) coupling reactions. The Fe/Cu-mediated coupling reaction can be used in the preparation of complex molecules, such as halichondrins and analogs thereof. In particular, the Fe/Cu-mediated ketolization reactions described herein are useful in the preparation of intermediates en route to halichondrins. ##STR00001##
