SAR studies of 2- o -substituted-benzoyl- and 2-alkanoyl-cyclohexane-1,3-diones as inhibitors of 4-hydroxyphenylpyruvate dioxygenase
摘要:
Inhibition studies of 4-hydroxyphenylpyruvate dioxygenase (HPPD) with various synthesized 2-o-substituted-benzoyl- and 2-alkanoyl-cyclohexane-1,3-diones suggest that the presence of a strongly electronegative group at the ortho position and the conformation of the benzene ring moiety on the benzoylcyclohexane-1,3-dione inhibitors are crucial for potent HPPD inhibition.

A straightforward 2-step parallel synthesis for structurally diversified spiro compounds is developed. 2-Bromobenzoic acids are used as common building blocks to couple with a series of conjugated enoles or enamines. Sequential intramolecular free radical Michael additions lead to formation of spirobenzolactones, spirobenzolactams, spirobenzolactone-lactams, spiorbenzolactone-thiolactones, spiordilactones
