The cyclophane in [2+2] structure for recognition guest was synthesized from 1,4-bis(benzimidazol-2-yl)butane and 1,4-dibromobutane.The reaction conditions were examined including reaction temperature,basicity and its quantity ratio.The structure was confirmed on the basis of IR,1H NMR and MS.
A novel pyrethroid——4-allyl-2-methoxyphenyl-2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropanecarboxylate is synthesized and its structure is confirmed on the basis of UV,MS,1H NMR and elemental analysis.The bioactivity is tested primarily with mosquito and the relation to structure is discussed.
