Hexahydro-, 5b-1 and 6a,f,1 and tetrahydrophospholo[2,3-d]isoxazoles 8, 9 and 10 were synthesized by 1,3-dipolar cycloaddition of nitrones 3b-1 and benzonitrile oxide (4) to 2,3-dihydro-1-phenyl-1H-phosphole 1-oxide (1) and 2,3-dihydro-1-ethoxy-1H-phosphole 1-oxide (2). The structural assignment to the compounds was confirmed by an X-ray study of two compounds of the series 5a and 5m. The compounds
通过将1,3-偶极环3b-1和氧化苄腈(4)进行1,3-偶极环加成反应合成六氢,5b-1和6a,f,1和四氢磷[2,3- d ]异恶唑8、9和10。 3-二氢-1-苯基-1 H-磷酰基1-氧化物(1)和2,3-二氢-1-乙氧基-1 H-磷酰基1-氧化物(2)。通过对5a和5m系列的两种化合物的X射线研究证实了这些化合物的结构归属。该化合物作为杀真菌剂对葡萄小单胞菌表现出良好的活性。葡萄藤上和苹果上的灰葡萄孢菌。化合物5a-d显示出弱至中等的除草剂活性。
