【Chemical Properties】
Lub cev muaj zog: Ethyl 4-chloroacetoacetate yog cov kua tsis muaj xim uas muaj ntxhiab tsw tshwj xeeb. Solubility: Nws tuaj yeem yaj hauv ntau yam organic solvents, xws li ether, chloroform thiab acetone. Stability: Nws yog qhov ruaj khov nyob rau hauv chav tsev kub, tab sis decomposition cov tshuaj tiv thaiv yuav tshwm sim thaum rhuab los yog nyob rau hauv kev sib cuag nrog muaj zog oxidants. Reactivity: Nws tuaj yeem siv los ua tus neeg sawv cev acylating kom hnov mob nrog cawv los ua esters. Nws kuj tseem tuaj yeem hloov pauv cov tshuaj tiv thaiv nrog nucleophilic reagents los hloov cov tshuaj chlorine atoms. Tsis tas li ntawd, nws tuaj yeem koom nrog ester hydrolysis cov tshuaj tiv thaiv.
【Daim ntawv thov】
Pharmaceutical intermediates: Ethyl 4-chloroacetoacetate yog ib qho nruab nrab rau atorvastatin calcium thiab oxiracetam, uas yog cov tshuaj muaj txiaj ntsig zoo rau kev kho mob plawv thiab paj hlwb. Oxiracetam yog ib qho tshuaj uas muaj qee yam cuam tshuam rau kev ntxiv dag zog rau kev nco thiab rov ua kom lub hlwb ua haujlwm. Organic synthesis: Raws li ib qho ethyl acetate anhydride (ketoene) reagent nyob rau hauv cov organic synthesis tshua, nws yog siv los tsim cov tebchaw xws li esters, amides thiab ketones. Cov tshuaj tiv thaiv condensation: Nws yog siv los ua ib qho kev ua kom reagent rau ketoene reagents hauv Knoevenagel condensation tshua. Carbonylation ntawm ketones: Raws li tus neeg sawv cev acylating hauv cov organic synthesis, nws koom nrog cov tshuaj tiv thaiv carbonylation ntawm ketones. Amidation: Raws li acyl hloov reagent nyob rau hauv cov organic synthesis, nws koom nyob rau hauv lub amidation ntawm hydroxylamine nyob rau hauv lub Curtius rearrangement cov tshuaj tiv thaiv.
