Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. 196597-78-1, Name is 1,2,6,7-Tetrahydro-8H-indeno[5,4-b]furan-8-one, belongs to thiazines compound, is a common compound. In a pantent, author is Shestakov, Alexandr S., once mentioned the new application about 196597-78-1, Synthetic Route of 196597-78-1.
Alkylation of 1,3-benzothiazin-4-one 2-oxo-, 2-arylimino-, and 2-thioxo derivatives
Sodium salt of 3De -benzo[e][1,3]thiazine-2,4-dione is easily alkylated at position 3. In the case of 2-(arylimino)-2,3-dihydrobenzo[e][1,3]-thiazin-4-ones, the alkylation reaction at this position occurs regioselectively. Alkylation of 2-thioxo-2,3-dihydrobenzo[e][1,3]thiazin-4-one under the same conditions produced regioisomers, but S-alkylation at the exocyclic sulfur atom occurred in the presence of triethylamine. The reaction of 1-(4-oxo-3,4-dihydrobenzo[e][1,3]thiazin-2-ylidene)guanidine with methyl anthranilate led to the formation of tetracyclic quinazolinD3/4[2,1-b]quinazolinedione.
The proportionality constant is the rate constant for the particular unimolecular reaction. You can get involved in discussing the latest developments in this exciting area about 196597-78-1. Synthetic Route of 196597-78-1.
