One-step Catalytic Synthesis and Herbicidal Activity of (1S,4R)-4,7,7-Trimethyl-6-oxabicyclo[3.2.1] octane-1,4-diol
摘要
Abstract
(1S,4R)-4,7,7-trimethyl-6-oxabicyclo[3.2.1] octane-1,4-diol(2) was synthesized from terpinolene by using hexadecyl pyridinium peroxo heteropolyoxomolybdotungstate( HPP) as redox-acid bifunctional catalyst and 30%( mass fraction) H2 O2 as oxidant.The optimal conditions for the reaction were terpinolene 4 mmol, HPP catalyst 7.35%( calculated by the mass of terpinolene), solvent chloroform 0.8 mL, the reaction material ratio(molar ratio of H2O2 and terpinolene) 3, reaction temperature 35℃, reaction time 6 h.Under these conditions, the conversion rate of terpinolene reached 100%and the yield of compound 2 reached 29%.The molecular structure was identified by means of IR, NMR and single crystal X-ray diffraction. The preliminary herbicidal activity assay indicated that compound 2 showed excellent inhibitory effect against the root growth and shoot elongation of ryegrass(Lolium rigidum);the inhibition rates against the root growth and shoot elongation were up to 91.8%and 80.7%, respectively, at the concentration of 120 mmol/L.Compared with the reported 1, 8-cineole, compound 2 had better inhibitory effect on ryegrass.关键词
