The steroidal plant growth-promoting lactone epocholeone has attracted much attention due to its great potential applications in agriculture. Herein, we report a chromatography–free synthesis of the epocholeone using a potassium osmate-catalyzed asymmetric dihydroxylation as the key reaction. Compared to the existing literature routes, the current protocol features low–toxicity reagents, simple operations
The present invention relates to an herbicide combination comprising components (A) and (B), where (A) denotes one or more compounds or salts thereof from the group described by the general formula (I):
in which R
1
is a halogen; R
2
is hydrogen; and R
3
is hydroxyl, or R
2
and R
3
together with the carbon atom to which they are attached are a carbonyl group C═O; and R
4
is hydrogen or methyl, and (B) denotes one or more herbicides which do not belong to the group of the dimethoxytriazinyl-substituted difluoromethanesulfonylanilides.
