Fasalada kiimikada:Xerooyinka nitrogen -> xeryahooda kale ee nitrogen
Dhoola cadeynta canonical:C1ccc (cc1) n = c = nc2ccccc2
Sharraxaad:Diyaaradda Gawaarida Gawaarida waxaa loo isticmaalaa in loo isticmaalo kimistariga Pettory sida isku-darka isku-darka. Waa mid xanaaq badan oo dareen ah, oo sababay maqaalka maqaarka ee farmashiyaha iyo farmashiistaha.
Adeegsiga:In isku-darka loo yaqaan 'pept'. Alaabtan waxaa badanaa lagu isticmaalaa Amikathine, Glutathiond-ka, iyo sidoo kale isku-darka aashitada aashitada, aldehyde, ketone, isgocyanate; Markii loo isticmaalo sidii qaadashada fuuq-baxa wakiilka wakiilka, waxay ka falcelisaa Diyaaraddaclohehyleyn iyada oo loo marayo fal-celin-gaaban oo ku saabsan fal-galka waqtiga-gaaban heerkulka caadiga ah. Alaabtaani sidoo kale waxaa loo isticmaali karaa isku-darka peptis-ka iyo nalka aashitada. Way fududahay in la isticmaalo sheygan si aad uga jawaabto xarunta 'Carboxy' oo bilaash ah iyo kooxda amino-good ee peptide. Alaabtaani si ballaaran ayaa loo isticmaalaa caafimaadka, caafimaadka, sameynta iyo alaabada bayoolaji, iyo meelaha kale ee isku-darka ah. N, n'-douniclohlohehylcarBarbodide waa carbiodibigide loo isticmaalo lammaanaha amino acids inta lagu gudajiro peptidesis. N, n'-doondlohylcarbodide waxaa loo isticmaalaa in wakiil fuuq-baxa loogu talagalay diyaarinta amni-adatir, ketones, nitriles iyo sidoo kale is-kala-sooca iyo election ee aalkolada dugsiga sare. DiniclohexylcarBilBarbodide waxaa loo isticmaalaa inuu yahay wakiil fuuq-baxa heerkulka qolka ka dib marka la eego falcelinta gaaban, ka dib sheyga falcelinta ka dib Dabcaanka ayaa ah Dicyhehyleriya. Shaygu waa mid aad u yar oo jilicsan oo ku jirta dareeraha dabiiciga ah, sidaa darteed si sahlan kala tagga sheyga falcelinta.
Hordhac faahfaahsan
DitryclohlohylBurBarBarimimide (DCC) waa mid si caadi ah loo isticmaalo ee isku-darka dabiiciga ah. Waa adag oo caddaan ah oo ku dhexjirta biyaha oo ku milmaysa ku jirta solvents dabiici ah sida ethyly acetate iyo dichloromethane.
DCC waxaa ugu horreyn loogu isticmaalaa sidii wakiil lammaane oo ku yaal Pettides-ka iyo falcelin kale oo ku lug leh sameynta dammaanadaha. Waxay kor u qaadaa uumiga 'Carboxylic acids acids', taasoo horseedaysa abuurista amni-ga. Waxay tan ku fulisaa iyada oo ay ku shaqeyso kooxda aashitada ee carboxylic-ka oo fududeeya weerarkii nucleophic ee kaarboon-ka-qaadeyaasha carbonyl.
Marka lagu daro synthesis peptidesis, DCC waxaa sidoo kale loo isticmaalaa falcelinno kale oo kala duwan oo dabiici ah, sida fal-celinta iyo falcelinta xilliyeed. Waxaa loo shaqaysan karaa si ay u sameeyaan esters acids carxulic acids iyo aalkolo, iyo in loo beddelo qalabka loo yaqaan 'carborides acid' (sida chlorides acid, aciddrorides acid, iyo estaro firfircoon) galabta.
DCC waxaa lagu yaqaanaa wax ku oolnimadeeda sare ee kor u qaadida qaab dhismeedka xidhiidhka ee xilliga iyo is-waafajinta oo leh kooxo badan oo shaqeynaya. Si kastaba ha noqotee, waxaa sidoo kale loo arkaa inay tahay qoyaan-xasaasiyad-xasaasi ah oo si fudud ayaa loo burburin karaa markay soo gaadho biyaha ama huurka badan. Sidaa darteed, sida caadiga ah waxaa loo maareeyaa laguna kaydiyaa xaaladaha xiisaha leh.
Waa muhiim inaad qaadato taxaddarrada lagama maarmaanka ah markaad la shaqeyneyso DCC, maadaama ay u xanaaqdo maqaarka, indhaha, iyo nidaamka neefsashada. Hawo hawo habboon iyo qalab ilaalin shaqsiyeed waa in la istcimaalaa inta uu maareeyo.
Isticmaal
Diyaaradda DitryclohehylcarBarbodide (DCC) waxay ka heleysaa codsiyo kala duwan oo ku saabsan isku-darka dabiiciga ah, gaar ahaan duurka ee kimistariga Pettariga. Halkan waxaa ku yaal dhowr codsi oo caan ah oo ah DCC:
Pet Synthesis:DCC waxaa caadi ahaan loo adeegsadaa wakiilka lammaanaha ee Pettesis-ka Synthesis si uu ugu biiro amino acids oo uu sameeyo dammaanado. Waxay kor u qaadaa falcelinta uumiga ee ka dhexeeya kooxda carboxyl kooxda hal amino acid iyo kooxda amino ee mid kale, taasoo horseedaysa samaynta xasaasiyadda pept.
Fal-celinta ESTIONIMINIXING:DCC waxaa loo isticmaali karaa in lagu beddelo aashitada carbboxylic acids ester-ka iyadoo ay ka falceliyaan khamri. Joogitaanka DCC, gaariga-carboxylic acid waa la shaqeynayaa, taasoo u oggolaaneysa weerarka nucleophilikophilikoplic aalkolada si ay u dhisaan estarta. Fal-celintaani waxay waxtar u leedahay isku-darka esters ee codsiyada kala duwan.
Falcelinta Nicmada:DCC waxay fududeyn kartaa cibaadada aashitada carbboxylic, chlorides acid, aashitada aashitada, iyo estarooyinka firfircoon. Waxay u oggolaaneysaa falcelinta ka dhexeysa xargaha aashitada ee carboxylic acid ah iyo amine si ay u sameeyaan dammaanad. Codsigan wuxuu ku helaa adeegsi isku-darka isku-darka ee Caadiga ah, oo muhiim u ah nidaamyada bayoolojiga iyo kiimikada ee kala duwan.
Falcelin UGI:DCC waxaa loo isticmaali karaa falcelinta dadka dalka UG, oo ah fal-celin badan oo iskudhaf ah oo ku lug leh uumiga ee uumiga, isocyanide, xarun carbonyl, iyo aashito. DCC waxay gacan ka geysaneysaa inaad ku dhaqaaqdo kooxda carboxyl-ka ee aashitada, taasoo u oggolaaneysa inay ka falceliso amine oo ay sameeyaan dammaanad maahmaah ah.
Scors synthesis:DCC waxay inta badan ka shaqaysaa warshadaha dawooyinka loogu talagalay isku-darka musharixiinta daroogada iyo maaddooyinka dawooyinka firfircoon (APIS). U adeegsiga PetTidesis-ka PetTides, gudihiis, iyo isbadal kale oo muhiim ah ayaa ka dhigaya mid lama huraan ah oo ku saabsan daahfurka daroogada iyo hanaanka horumarinta.
Waxaa xusid mudan in DCC ay leedahay dalabyo kale oo kala duwan oo ku jira isku-darka dabiiciga ah, oo ay ku jiraan samaynta uliyayaasha, carbamates, iyo hydruzides. Arayada iyo is-waafajinta oo leh kooxo firfircoon oo kala duwan ayaa ka dhigaya aalad qiimo u leh sanduuqa qalabka kiimikada.
