Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Formula: C6H14N2, Which mentioned a new discovery about 20439-47-8
SINTESIS, ESTUDIO DINAMICO POR RMN Y CALCULOS TEORICOS DE HEXAHIDRO- Y TETRAHIDROQUINOXALINAS 2,3-DISUSTITUIDAS
The synthesis of 2,3-disubstituted hexahydroquinoxaline stereoisomers from 1,2-diaminocyclohexanes and the corresponding alpha-dicarbonylic derivatives and their oxidation to tetrahydroquinoxalines is described.Their 1H- and 13C-NMR spectra are analyzed and a 13C-DNMR study on cis 2,3-diphenyl-hexahydroquinoxaline 1a is carried out.The DeltaH*, DeltaS* and DeltaG* for the dynamic process of interchange between the two chair conformers of cis 1a are calculated.A theoretical study, using the semiempirical methods AM1 and PM3 of cis and trans 1a, as well as Ab initiocalculations, using 4-31G basis over optimized geometries by the semiempiric method PM3, of their analogues without phenyl substituents are reported.The DeltaH* values calculated are in agreement with the experimental value of cis 1a.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Formula: C6H14N2, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 20439-47-8
