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

2 (5H) - I-Furanone yi-lactone eneempawu eziqhelekileyo ze-ester, ezinje ngokunciphisa amandla kunye ne-ammonolysis; Iqulethe iibhondi ezimbini ezidityaniswe nee-esters, i-Michael addition reaction inokwenzeka; Ngenxa yokunxibelelana kwayo ne-oksijini kunye nesiphumo sokurhoxiswa kwe-electron yamaqela e-ester adluliselwa ngeebhondi ezimbini, iqela layo le-methylene line-asidi kwaye linokususwa kwi-hydrogen ziziseko eziqinileyo.

Isicelo

2 (5H) - I-Furanone yi-organic heterocyclic compound, eyona butenolide ilula, ebonakala njengolwelo olungenambala kubushushu begumbi. Ifomyula yayo yolwakhiwo yi-γ - crotonyl lactone, eyinto yokuqala kwiimolekyuli ezininzi ezisebenzayo kumayeza. Ulwakhiwo lwayo lufumaneka rhoqo kwiimolekyuli ezisebenzayo ezifana nee-antibiotics, ii-antimicrobials, amayeza okulwa nethumba, kunye namayeza okulwa neentsholongwane.
