Cov Ntawv Thov
3,4,5 {-} Lub cev tawv nqaij feem ntau yog siv nyiaj nruab nrog hauv chaw muag tshuaj thiab synthes synthesis. Nws pabcuam ua lub tsev thaiv kev npaj rau kev npaj ntawm cov tebchaw bioaction, suav nrog tshuaj tiv thaiv anticancer, anti {}} kev kho cov lwg me me. Qhov sib xyaw kuj tseem ua haujlwm hauv synthesis ntawm dyes, agrochemicals, thiab cov tshuaj tshwj xeeb uas yuav tsum tau txiav txim siab ntawm scaffolds. Ib qho ntxiv, nws tau siv hauv kev tshawb fawb rau kev txhim kho ntawm tshiab heterocyclic tebchaw thiab cov qauv-kev ua ub no kev kawm.
Cov txiaj ntsig
