Total synthesis method for xinaomycin

The invention belongs to the technical field of pharmaceutical chemistry and organic synthesis, and aims to provide a chemical total synthesis method for xinaomycin. The method comprises the steps of:using D-galactose and the like as raw materials, firstly carrying out 8 steps of reactions to obtain a compound 14, then performing condensation on the compound 14 and uracil to obtain a compound 15,performing 4 steps of reactions to obtain a compound 19, performing condensation on the compound 19 and a compound 6 to obtain a compound 20, and finally removing an ester protecting group and a Cbzprotecting group in turn, so as to obtain the natural product xinaomycin. The total synthesis method of the present invention is a method for synthesizing the natural product xinaomycin for the firsttime. The total synthesis method has the advantages of high product purity, low cost, simple operation and the like.

Glucose positions affect the phloem mobility of glucose-fipronil conjugates

In our previous work, a glucose-fipronil (GTF) conjugate at the C-1 position was synthesized via click chemistry and a glucose moiety converted a non-phloem-mobile insecticide fipronil into a moderately phloem-mobile insecticide. In the present paper, fipronil was introduced into the C-2, C-3, C-4, and C-6 positions of glucose via click chemistry to obtain four new conjugates and to evaluate the effects of the different glucose isomers on phloem mobility. The phloem mobility of the four new synthetic conjugates and GTF was tested using the Ricinus seedling system. The results confirmed that conjugation of glucose at different positions has a significant influence on the phloem mobility of GTF conjugates.
