Folasaga
4-Amino-tetrahydropyran (faʻapitoa foi o le 1-amino-4-hydro-epoxy-2,3,5,6-tetrahydropyran) o se faʻalapotopotoga faʻapitoa. O se vai e leai se lanu i le samasama samasama ma se fausaga e tutusa ma le amino vaega galue ma se mama epoxy.
O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le 4-amino-tetrahydropyran:
Tulaga lelei:
- Fa'aaliga: leai se lanu e o'o ile vai samasama;
- Solubility: solu i le vai, ava malosi ma eter solvents;
- Mea tau vailaʻau: O se nucleophile reactive e mafai ona auai i le tele o gaioiga faʻaola, e pei o le nucleophilic substitution reactions, tali tatala mama, ma isi.
Fa'aaogā:
- 4-amino-tetrahydropyran e mafai ona faʻaaogaina e avea o se reagent i le faʻaogaina o meaola ma e mafai ona faʻaaogaina e faʻapipiʻi ai mea faʻapitoa eseese, e pei o amides, carbonyl compounds, ma isi;
- I le alamanuia vali, e mafai ona faʻaaogaina i le tuʻufaʻatasia o vailaʻau faʻasolosolo.
Metotia:
E tele auala e saunia ai le 4-amino-tetrahydropyran, ma o se tasi lea o auala masani e faʻaaogaina:
Na faʻaopoopoina le kasa amonia i le tetrahydrofuran (THF), ma i le maualalo o le vevela, na maua ai le 4-amino-tetrahydropyran e ala i le faʻamaʻiina o le benzotetrahydrofuran inoculation.
Fa'amatalaga Saogalemu:
- 4-amino-tetrahydropyran o se vai mumu e tatau ona teuina i se nofoaga malulu, faʻaleleia lelei, mamao ese mai le afi;
- 'Alo'ese mai le manava, pa'i pa'u ma fe'ai mata a'o fa'aoga, ma fufulu vave i le vai pe a tupu fa'afuase'i;
- Aloese mai le fa'atupuina o kasa mu, ausa po'o le pefu a'o fa'agaioiga;
- Fa'aaoga mea e puipui ai e pei o totigilima, mata tioata ma lavalava puipui pe a fa'aaoga;
