Cov Ntawv Thov
(R) - (-}}}}}}}}}}}}} ecochemical, thiab zoo tshuaj lom neeg. Nws tau ua haujlwm hauv kev npaj ntawm -Vockers, chiral nigands, thiab enantiomerically ntshiab nquag cov khoom xyaw tshuaj (API). Nws charchal center ua rau nws muaj txiaj ntsig rau cov synthesis, ua rau cov khoom siv asymmetemesis, ua kom cov khoom siv ua haujlwm zoo nrog cov enantiomouric purity. Ib qho ntxiv, nws yog siv nyob rau hauv cov synthesis ntawm heterocyclic tebchaw, amino acid derivatives, thiab lwm yam molecules hauv cov tshuaj chemistry thiab kev tshawb fawb tshuaj lom neeg.
Cov txiaj ntsig
Cov txiaj ntsig ntawm (r) - (-}}}}}}}}}} Lub amino thiab hydroxyl pawg cia ntau yam kev hloov tshuaj lom, suav nrog acylation, alkylation tsis tshua muaj kev cuam tshuam. Nws enantiomeric purity pab cov synthesis ntawm stereOchemically txhais cov tebchaw, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm roj ntsha thiab cov kws ua tshuaj ua haujlwm hauv kev tsim tshuaj. Qhov sib xyaw ua ke yog ruaj khov, soluble hauv cov txheej txheem organic, thiab tau tshaj nrog cov txheej txheem hluavtaws txheem, ua rau cov kev siv hluav taws xob zoo thiab muaj zog thiab cov ntawv thov kev lag luam.
