Iyini i-2(5H)-Furanone CAS 497-23-4?

2 (5H) - I-Furanone iyi-lactone enezici ezivamile ze-ester, ezifana nokunciphisa kanye ne-ammonolysis; Iqukethe amabhondi aphindwe kabili ahlanganiswe nama-esters, ukusabela kokwengezwa kukaMichael kungenzeka; Ngenxa yokuxhumana kwayo ne-oksijini kanye nomphumela wokuhoxiswa kwe-electron wamaqembu e-ester adluliselwa ngezibopho eziphindwe kabili, iqembu lalo le-methylene line-acidity futhi lingaba ne-hydrogen ngenxa yezisekelo eziqinile.

Isicelo

2 (5H) - I-Furanone iyinhlanganisela ye-organic heterocyclic, i-butenolide elula kakhulu, ebonakala njengoketshezi olungenambala ekamelweni lokushisa. Ifomula yayo yesakhiwo ithi γ - crotonyl lactone, okuyindawo eyandulela yama-molecule amaningi asebenzayo emithini. Ukwakheka kwayo kuvame ukutholakala kuma-molecule e-bioactive afana nama-antibiotics, ama-antimicrobials, ama-anti-tumor drugs, nezidakamizwa ezilwa namagciwane.
