Synthetic Route of 69-78-3, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 69-78-3, Name is DTNB, SMILES is O=C(O)C1=CC(SSC2=CC=C([N+]([O-])=O)C(C(O)=O)=C2)=CC=C1[N+]([O-])=O, belongs to indole-building-block compound. In a article, author is Kumar, Anil, introduce new discover of the category.
A manganese-catalyzed C-H bond alkenylation of indoles at C2-position with 4-hydroxy-2-alkynoates leading to concomitant lactonization under removable directing group strategy has been disclosed. This lactonization strategy exhibits regioselectivity, a broad substrate scope, and a good functional group tolerance furnishing the products in low to high yields. The regioselectivity is guided by the electronic effect of the ester group as well as the steric bulk at the C4-position of the 4-hydroxy-2-alkynoates. After the reaction, the directing group has been readily removed to obtain N-H free indole.
Synthetic Route of 69-78-3, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 69-78-3.
