Piquerol diacetate

Other hand, H+-uptake, basal and uncoupled electron transport were not affected. The acetylation of 26a yielded piquerol diacetate (26b) increasing its lipophilicity and photophosphorylation capacity [53]. 

It is well known that synthetic phenol and hydroquinones have herbicidal activity [54-56]. This finding led us to transform piquerol A to related compounds and examine their effects on the weeds Amaranthus hypocondriacus and Echinocloa crusgalli [123]. Piquerol A diacetate (26b), as well as, the benzylic alcohol (27), dialkilhydroquinone (28), and phenolic (29, 30,31) derivatives were prepared as indicated below "Fig. (7)."...
