Isicelo:

I-Potassium Bis(trimethylsilyl)amide (0.5M Isixazululo ku-Toluene) (imvamisa ifushanisiwe njenge-KHMDS) (CAS: 40949-94-8) isisekelo esiqinile, esingeyona i-nucleophilic esine-pKa ehlawumbisela engu-26 (qhathanisa ne-lithium diisopropylamide, ku-36 ).Itholakala ngokwezentengiselwano njengesiqinile futhi njengesixazululo ezixukwini ezihlukahlukene (isb. THF, 2Me-THF, toluene, ne-MTBE).Ama-reagents afanayo afaka i-lithium bis(trimethylsilyl)amide (LiHMDS) kanye ne-sodium bis(trimethylsilyl)amide (NaHMDS).Isisekelo esiqinile se-non-nucleophilic megasteric.Ama-intermediate emithi, asetshenziswa ekukhiqizeni ama-cephalosporins okwenziwa.I-KHMDSi-reagent yamakhemikhali esetshenziswa ekulungiseni i-chromatography yoketshezi esebenza kahle kakhulu.Isetshenziselwa ukwakha ama-complexes azinzile nge-potassium, abese ehlukaniswa yikholomu.I-KHMDS iphinde isetshenziswe ocwaningweni lwamakhemikhali ezinto eziphilayo nanjenge-asymmetric synthesis catalyst.I-KHMDS iyisisekelo esiqinile esisetshenziswa kumakhompiyutha e-alkylation carbonyl.I-KHMDS isetshenziswa ekulungiseleleni i-5-Azacytidine, umuthi we-antineoplastic.Kusetshenziswa futhi ekulungiseleleni ama-agonists e-β3-AR asetshenziswa ekwakhiweni okulwa nokucindezeleka.Iphinde isetshenziswe njenge-reagent ekulungiseleleni izakhiwo ze-lanthanide ezisetshenziswa ekuphenduleni okukhethiwe kwamabhayisikili.
