Chemistry, like all the natural sciences, Safety of 3-Oxopentanedioic acid, begins with the direct observation of nature¡ª in this case, of matter.542-05-2, Name is 3-Oxopentanedioic acid, SMILES is O=C(CC(O)=O)CC(O)=O, belongs to thiazolidines compound. In a document, author is Velikorodov, A. V., introduce the new discover.
Hetero-diels-alder reaction of 5-ylidene-4-sulfanylidene-1,3-thiazolidin-2-ones with N,N ‘-bis(methoxycarbonyl)-1,4-benzoquinone diimine
Hetero-Diels-Alder reaction of 5-(propan-2-ylidene)-4-sulfanylidene-1,3-thiazolidin-2-one with N,N’-bis(methoxycarbonyl)-1,4-benzoquinone diimine in boiling toluene afforded 87% of dimethyl 9,9-dimethyl-2-oxo-8a,9-dihydro-2H-thiochromeno[2,3-d][1,3]thiazole-5,8(3H,4aH)-diylidenedicarbamate. Analogous reactions of 5-benzylidene-, 5-{[4-(dimethylamino)phenyl]methylidene}-, and 5-[(2-hydroxyphenyl)-methylidene]-4-sulfanylidene-1,3-thiazolidin-2-ones led to the formation of the corresponding dimethyl 9-aryl-2-oxo-3,9-dihydro-2H-thiochromeno[2,3-d][1,3]thiazole-5,8-diyldicarbamates in 64-82% yield.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 542-05-2. Safety of 3-Oxopentanedioic acid.
