Khoom Description
3,4,6-Tri-O-benzyl-D-glucal yog cov khoom sib xyaw. Nws yog dawb crystalline hmoov, soluble nyob rau hauv cov organic solvents xws li dichloromethane thiab diethyl ether, insoluble nyob rau hauv dej.Tri-O-benzyl-D-glucal kuj ruaj khov nyob rau hauv huab cua, tab sis ntev raug rau lub teeb ci yuav tsum tau zam kom tsis txhob degradation.
Kev siv:
3,4,6-Tri-O-benzyl-D-glucal yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab tuaj yeem siv los ua ke rau lwm cov tshuaj bioactive.
Txoj Kev Npaj:
Tri-O-benzyl-D-glucenose tuaj yeem npaj los ntawm reacting D-glucose nrog sodium hydroxide thiab triphenylaldehyde. Thaum cov tshuaj tiv thaiv, triphenylaldehyde ua raws li kev tiv thaiv hydroxyl pawg.
Tom qab cov tshuaj tiv thaiv tiav lawm, pab pawg tiv thaiv tuaj yeem raug tshem tawm los ntawm kev siv cov kua qaub lossis txo tus neeg sawv cev kom tau txais tri-O-benzyl-D-glucenose.
