Method for synthesizing prohexadione calcium and trinexapac-ethyl

The invention discloses a method for synthesizing prohexadione calcium and trinexapac-ethyl. The method comprises the following steps: reacting diethyl maleate (alpha, beta unsaturated carboxylic acid) with sodium ethoxide to obtain high-purity intermediate compound as shown in a formula II, and preparing prohexadione calcium and trinexapac-ethyl from the compound as shown in the formula II. In the reacting steps for preparing the compound as shown in the formula II, sodium ethoxide serving as a reactant participates in the reaction rather than a strong basic catalyst; a 1,3-cyclohexanedione compound is prepared from the intermediate compound as shown in the formula II and acetone under a reflux condition, and the total yield for the reaction of two steps can be 87 percent. The method has the advantages of low energy consumption, short reaction time, easy operation and the like by using the 1,3-cyclohexanedione compound as the intermediate, and can be used for preparing prohexadione calcium and trinexapac-ethyl with high yield.

SAR studies of 3-cyclopropanecarbonyloxy-2-cyclohexen-1-one as inhibitors of 4-hydroxyphenylpyruvate dioxygenase

Various 3-cyclopropanecarbonyloxy-2-cyclohexen-1-one 1 derivatives have been synthesized and tested as inhibitors of 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) from pig liver. The inhibition results indicated that well-positioned dicarbonyl groups as well as the cyclopropyl group of 1 were essential for potent inhibition. Substitution at the 2-position of the ring system has a significant effect on inhibitor potency, while the 5-position can undergo substantial variations and retain inhibitor potency. In the compounds examined, 2-chloro substituted 12 is the best inhibitor of all with IC50 of 15 nM, the rest of the synthesized analogues were less potent inhibitors than the parent compound.
