Selelekela
4-Amino-tetrahydropyran (e tsejoang hape e le 1-amino-4-hydro-epoxy-2,3,5,6-tetrahydropyran) ke motsoako oa lintho tse phelang. Ke mokelikeli o se nang 'mala ho isa ho o mosehla o mosehla ka sebopeho se ts'oanang le sehlopha sa amine sa amino le reng ea epoxy.
Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 4-amino-tetrahydropyran:
Boleng:
- Ponahalo: metsi a se nang 'mala ho isa mosehla o mosehla;
- Ho qhibiliha: ho qhibiliha ka metsing, joala le li-solvents tsa ether;
- Thepa ea lik'hemik'hale: Ke nucleophile e sebetsang e ka nkang karolo liketsong tse ngata tsa organic, joalo ka karabelo ea nucleophilic substitution, karabelo ea ho bula mehele, jj.
Sebelisa:
- 4-amino-tetrahydropyran e ka sebelisoa e le reagent ho organic synthesis mme e ka sebelisoa ho kopanya metsoako e fapaneng ea lintho tse phelang, joalo ka li-amides, metsoako ea carbonyl, joalo-joalo;
- indastering ea dae, e ka sebelisoa ha ho etsoa lidae tsa manyolo.
Mokhoa:
Ho na le mekhoa e mengata ea ho lokisa 4-amino-tetrahydropyran, 'me e latelang ke e' ngoe ea mekhoa e sebelisoang hangata:
Khase ea ammonia e ile ea eketsoa ho tetrahydrofuran (THF), 'me ka mocheso o tlaase, 4-amino-tetrahydropyran e ile ea fumanoa ka oxidizing benzotetrahydrofuran inoculation.
Lintlha tsa Tšireletseho:
- 4-amino-tetrahydropyran ke mokelikeli o tukang o lokelang ho bolokoa sebakeng se pholileng, se nang le moea o motlakase, hole le mollo;
- Qoba ho hema, ho kopana le letlalo le ho shebana le mahlo nakong ea tšebeliso, 'me u hlatsoe hang-hang ka metsi haeba u ka kopana ka phoso;
- Qoba ho hlahisa likhase tse tukang, mouoane kapa lerōle nakong ea ts'ebetso;
- Apara lisebelisoa tse nepahetseng tsa ts'ireletso tse kang liatlana, likhalase le liaparo tsa tšireletso ha u sebelisoa;
