Selelekela

N-Boc-L-Phenylglycine ke motsoako oa motsoako o entsoeng ka ho thehoa ha k'hemik'hale ea lik'hemik'hale pakeng tsa sehlopha sa amino (NH2) sa glycine le sehlopha sa carboxyl (COOH) sa benzoic acid. Sebopeho sa eona se na le sehlopha se sireletsang (Boc sehlopha), e leng sehlopha sa tert-butoxycarbonyl, se sebelisetsoang ho sireletsa ts'ebetsong ea sehlopha sa amino.

 

N-Boc-L-phenylglycine e na le thepa e latelang:

- Ponahalo: E tiileng ka kristale e tšoeu

- Solubility: E qhibiliha ka har'a lihlapi tse ling tsa organic, joalo ka dimethylformamide (DMF), dichloromethane, jj.

 

N-Boc-L-phenylglycine e atisa ho sebelisoa liketsong tsa mehato e mengata ho organic synthesis, haholo-holo bakeng sa motsoako oa metsoako ea peptide. Sehlopha se sirelletsang sa Boc se ka sireletsoa ke maemo a asiti, e le hore sehlopha sa amino se ka sebetsa hantle ebe se etsa karabelo e latelang. N-Boc-L-phenylglycine e ka boela ea sebelisoa e le motsoako oa ho haha ​​​​litsi tsa chiral ka peptide synthesis.

 

Tokisetso ea N-Boc-L-phenylglycine e etsoa haholo-holo ka mehato e latelang:

Glycine e na le esterified ka benzoic acid ho fumana benzoic acid-glycinate ester.

Ho sebelisa lithium borotrimethyl ether (LiTMP) reaction, benzoic acid-glycinate ester e ile ea hlahisoa 'me ea itšoara ka Boc-Cl (tert-butoxycarbonyl chloride) ho fumana N-Boc-L-phenylglycine.

 

- N-Boc-L-phenylglycine e ka 'na ea halefisa mahlo, letlalo le tsela ea ho hema 'me e lokela ho qojoa nakong ea tšebeliso.

- Lisebelisoa tsa ho itšireletsa tse kang liatlana tsa laboratori, likhalase tsa tšireletso, joalo-joalo li lokela ho apesoa nakong ea ts'ebetso.

- E lokela ho etsoa sebakeng sa laboratori e nang le moea o motle.

- Qoba ho kopana le li-oxidants le li-acid tse matla ha u li boloka.

- Haeba u metsoa kapa u hema, batla thuso ea bongaka hang-hang, tlisa setshelo sa motsoako, 'me u fane ka boitsebiso bo hlokahalang ba tšireletso ho ngaka.
