Methanesulfonic anhydride 丨 cas no 7143-01-3

Methanesulfonic anhydride 丨 cas no 7143-01-3 yog cov reasride siab heev tau siv raws li cov neeg sawv cev ntawm cov lus dab neeg hauv cov organic synthesis.

1. Cov tshuaj synthes synthesis reffent
A. Mountylation tus neeg sawv cev
Methanesulfonic anhydride 丨 cas?
● Haus → Ua ntawm Mesylates (Roso₂ch₃)
Amines → Ua raws Sulfonamides
● Phenols → tsim ntawm aryl mesylates
Mesylates yog cov pab pawg tau zoo tshaj plaws thiab feem ntau siv hauv kev hloov chaw thiab tshem tawm cov kev tawm tsam, tshwj xeeb yog hauv kev ua yeeb yam synthesis.
B. Tiv Thaiv Pab Pawg
Hauv peptide thiab carbohydrate synthesis, methanesulfonic anhydride yog siv rau:
Tiv thaiv cov pab pawg hydroxyl
● Ua kom muaj intermediat
● Txhim kho solubility thiab ruaj khov

2. Tshuaj Kho Mob thiab Tshuaj Kho Mob
Siv nyob rau hauv synthesis ntawm api intermediates thiab tshuaj-zoo li lwg me me
● Qhov tseem ceeb ntawm kev sib sau bioactive sulfonamides lossis hloov pauv dej cawv rau hauv cov pab pawg kom zoo dua
● Siv rau hauv kev tsim cov khoom ntawm prodrugs, qhov twg mesylates tuaj yeem tswj cov tshuaj tawm tshuaj

3. Polymer thiab Cov Khoom Siv Kev Tshawb Fawb
● Ua haujlwm ntawm polymers (piv txwv li, peg, polystyrene) nrog cov pab pawg mesyl kom ua solubility, lossis hla kev sib txuas lub peev xwm
● Siv nyob rau hauv cov kev hloov kho saum npoo rau kev tsim cov chaw seem ntawm cov polymers, cov yeeb yaj kiab, lossis cov resins

4. Kuaj cov ntawv thov
● nquag siv hauv kev tshawb fawb tshuaj lom neeg zoo, tshwj xeeb tshaj yog thaum muaj zog sulfonymation imagation yog xav tau
● Kev ua haujlwm hauv cov kev ua hauv hluavtaws uas muaj cov xwm txheej rhiab yuav tsum raug zam (tsawg dua cov kua qaub (tsawg dua li cov kab mob sulfony)

√ Muaj tseeb cuam tshuam hluav taws xob hauv electrophile
● Ntxiv ntau dua li methanesulfonyyl chloride, ua kom ceev ceev, txuag mesylation nyob rau hauv cov mob me me
√ nqus cov kev xav tau
● Ua cov khoom lag luam tsawg dua piv rau cov tshuaj sulfonyl
Tsis txhob tso cov xeb HCl thaum lub sijhawm
√ Dav Subtable
● Ua tau zoo nrog aliphaatic, muaj ntxhiab, thiab heterocyclic tebchaw
● Pab tau txiaj ntsig nyob rau hauv kev sib cav sib txawv los yog hluav taws xob-tsis muaj tseeb
Txhim kho molecular ruaj khov
● Mesylation tuaj yeem txhim kho cov cua sov thiab hydrolytic ruaj khov ntawm intermediates lossis kawg-cov khoom
√ Versatility hauv Synthesis
Tsim kom haum rau cov nplai thiab siv hluav taws xob hluavtaws hluav taws xob
