Research speed reading in 2021. Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. , Category: thiazines, 7143-01-3, Name is Methanesulfonic anhydride, molecular formula is C2H6O5S2, belongs to thiazines compound. In a document, author is Yavari, Issa, introduce the new discover.
A synthesis of functionalized arylthio-acrylates, benzo[b][1,4]thiazines and benzo[4,5]thiazolo[3,2-a]azepines from 2-methylbenzothiazole and acetylenic esters in aqueous media
Alkyl (Z)-3-((2-(N-((E)-3-methoxy-3-oxoprop-1-en-1-yl)acetamido)phenyl)thio)acrylates are obtained from the reaction between 2-methylbenzothiazole and alkyl propiolates in 70% aqueous alcohol, in moderate yields. When dialkyl acetylenedicarboxylates were used under similar conditions, tetra-alkyl 9,10-dihydrobenzo[4,5]thiazolo[3,2-a]azepine-7,8,9,10-tetracarboxylates, together with dialkyl 4-acetyl-3,4-dihydro-2H-benzo[b][1,4]thiazine-2,3-dicarboxylates were obtained in about 4:1 ratios. The stereochemistry of these products has been confirmed by X-ray diffraction.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 7143-01-3, in my other articles. Category: thiazines.
