Cov ntaub ntawv

Siv 2, 4-dipiperidon-1-formate tert-butyl formate yog cov synthesis ntawm phenoxymethyl-dihydrothiazolopyridone derivatives Reactants nyob rau hauv cov khoom, raws li ib tug xaiv zoo qauv modulator (PAM) ntawm metabolized glutamate 5 (mGlu5) receptor.
daim ntawv thov 2, 4-dioperidone-1-tert-butyl formate feem ntau yog siv los ua cov organic nruab nrab thiab cov tshuaj nruab nrab, thiab tuaj yeem siv rau hauv kev tshawb fawb thiab kev loj hlob ntawm cov txheej txheem tshuaj thiab tshuaj synthesis txheej txheem.
kev npaj Kauj ruam a: ntxiv EDCI (191.7g) rau DMF (400mL) tov ntawm 3-(tert-butoxycarbonylamino) propionic acid (189.2g, 1.0mol), meldamic acid (144.1g, 1.0mol) thiab DMAP (135.0g, 1.1mol) ) txias los ntawm dej khov da dej, 1.0mol). Qhov tshwm sim reactants tau nplawm ib hmos ntawm chav tsev kub. Cov tshuaj tiv thaiv yog quenched nrog 200mL
H2O. Qhov sib xyaw ua ke tau ntxiv dropwise rau H2O (2.0L) nyob rau hauv cov neeg kho tshuab stirring. Cov khoom tau raug lim thiab ntxuav kom huv si nrog dej rau pH 7 kom tau txais cov khoom (283g, 90% tawm los). Kauj Ruam B: Kev daws ntawm 3-(2, 2-dimethyl-4, 6-dioxo-1, 3-dioxan-5-yl)-3-oxopropylcarbamate tert-butyl ester (100g, 317.46mmol) hauv toluene (1500mL) yog rhuab ntawm 100 ° C rau 4 teev. Cov reactants yog txias rau chav tsev kub thiab concentrated nyob rau hauv lub siab txo kom tau ib tug crude khoom. Cov khoom (56g, 83% tawm los) yog purified los ntawm MTBE-sib tsoo.
