据Jelinek报道,N,N-二烷基-氨基甲酰基膦酰胺酯类化合物具有抑制植物生长的活性,能影响多种植物的开花和坐果。为探讨这类化合物的合成方法、结构与活性的关系,从而筛选出高效低毒的除草剂,本文合成了通式为RO(R′NH)P(O)C(O)-NHR~2的10种新化合物(表1)。对于合成方法进行了初步探讨,其中方法Ⅱ未见文献报道。 According to Jelinek, N, N-dialkyl-carbamoyl phosphonamidates inhibit plant growth and can affect the flowering and fruit setting of many plants. In order to explore the relationship between the synthesis method, structure and activity of these compounds, and to screened the herbicide with high efficiency and low toxicity, we synthesized the compound of general formula RO (R’NH) P (O) C (O) -NHR ~ 2 Ten new compounds (Table 1). For the synthesis of a preliminary study, in which method Ⅱ has not been reported in the literature.
