Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.6118-51-0, Name is exo-3,6-Epoxy-1,2,3,6-tetrahydrophthalic Anhydride, SMILES is O=C1OC([C@@]2([H])[C@](O3)([H])C=C[C@]3([H])[C@]21[H])=O, belongs to thiazolidines compound. In a document, author is Ansari, Monish Arbaz, introduce the new discover, Quality Control of exo-3,6-Epoxy-1,2,3,6-tetrahydrophthalic Anhydride.
Rhodium(II)-Catalyzed Annulative Coupling of beta-Ketothioamides with alpha-Diazo Compounds: Access to Highly Functionalized Thiazolidin-4-ones and Thiazolines
An operationally simple and efficient one-pot protocol for the synthesis of highly functionalized thiazolidin-4-ones and thiazolines has been devised via Rh(OAc)(2)-catalyzed annulative coupling of beta-ketothioamides with diazo compounds under mild reaction conditions for the first time. This double functionalization of diazo compounds proceeds via selective S-alkylation followed by intramolecular N-cyclization enabling the formation of C-S and C-N bonds at moderate temperature. Notably, the product possess Z-stereochemistry with regard to the exocyclic C=C double bond at the 2-position of the ring. Further, the synthetic utility of the strategy has been revealed to 2,3-dihydrobenzo[d]thiazoles. Remarkably, atom economy and tolerance of a wide range of functional groups are added characteristics to this strategy.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 6118-51-0 is helpful to your research. Quality Control of exo-3,6-Epoxy-1,2,3,6-tetrahydrophthalic Anhydride.
