摘　　要：自降解绿色农药对环境保护有重要意义。以苯硼酸为催化剂,1,4-苯二酚和α,β-不饱和醛为原料,在质子酸作用下首次合成了绿色农药中间体——羟基取代苯并吡喃化合物(HBPR),其结构经1H NMR,13C NMR,MS(ESI)和元素分析表征。并研究了目标化合物的自降解性能。结果表明:化合物在自然光照射下显示出与早熟素类似的自降解特性。Self-degradation pesticides have great significance to environmental protection.A novel hydroxyl substituted benzopyran compound(HBPR)was synthesized in the presence of br nsted acid,using phenylboronic acid as catalyst,hydroquinone andα,β-unsaturated aldehyde as material.The structure was characterized by^1H NMR,^13C NMR,MS(ESI)and elemental analysis.In addition,the self-degradation property was investigated.The results indicated that HBPR displayed similar self-degradation property to precoceneⅡunder daylight.
