I-Hazard Note irritant
I-2 (5H) -I-Furanone (γ-Crotonolactone) (i-CAS: 497-23-4) i-heterocyclic organic compound esetyenziswa ngokubanzi kumalungiselelo okwenziwa kweemveliso zonyango.
I-2 (5H) -I-Furanone iyona crotonolactone elula, ifomyula yayo yesakhiwo yi-γ-crotonyl lactone, into engaphambili yezinto ezininzi ezisebenzayo zamachiza, kwaye isakhiwo sayo sifumaneka ngokuqhelekileyo kwiimolekyuli ze-bioactive, ezifana ne-antibiotics, antibiotics, anti- ithumba kunye neziyobisi antiviral.
I-2 (5H) -I-Furanone iqeshwe ekulungiseleleni i-5-ifakwe endaweni ye-2 (5H) i-furanones (i-gamma-butenolides) eyenziwa yi-aminothiourea engasebenziyo kunye ne-aminosquaramide organocatalysts ngokuphendula ngokuthe ngqo kwe-aldol kunye ne-aldehydes enamakha.Ngaphaya koko, isetyenziswa ekudityanisweni kwee-lignans nguMichael ukongeza.Ukongeza kule nto, isetyenziswe kwiimpendulo ze-Michael-Aldol zamacandelo amathathu kunye ne-aldehyde kunye ne-thiolate okanye i-carbanion.
Umsebenzi webhayoloji: 2(5H)-Furanone yimetabolite engapheliyo.
