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

I-2 (5H) - I-Furanone yi-lactone eneempawu ze-ester eziqhelekileyo, ezifana nokunciphisa kunye ne-ammonolysis; Iqulathe iibhondi eziphindwe kabini ezidityaniswe nee-esters, ukusabela kokongeza kukaMichael kunokwenzeka; Ngenxa yokunxibelelana kwayo neoksijini kunye nesiphumo sokurhoxiswa kwe-electron yamaqela e-ester athunyelwa ngeebhondi eziphindwe kabini, iqela layo le-methylene line-asidi kwaye linokuba ne-hydrogen ehluthwe yiziseko ezinamandla.

Isicelo

I-2 (5H) - I-Furanone yi-organic heterocyclic compound, eyona butenolide elula, ebonakala njengolwelo olungenambala kwiqondo lokushisa. Ifomula yayo yesakhiwo ngu-γ - i-crotonyl lactone, eyona nto i-precursor yezinto ezininzi ezisebenzayo kumachiza. Ulwakhiwo lwayo luqhelekileyo lufumaneka kwiimolekyuli ze-bioactive ezifana ne-antibiotics, i-antimicrobials, i-anti-tumor drug, kunye ne-antiviral drug.
