New Advances in Chemical Research in 2021. In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1612-65-3, name is 2-Methyl-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery. Synthetic Route of 1612-65-3
Conformationally constrained, 1,2,3,4-tetrahydroisoquinoline (TIQ) analogs of central stimulant (e.g. amphetamine) and hallucinogenic (e.g. DOM) phenylalkylamines were prepared and evaluated to determine the contribution to activity of this conformational restriction. The amphetamine-related TIQs failed to produce locomotor stimulation in mice and did not produce amphetamine-appropriate responding in tests of stimulus generalization in (+)amphetamine-trained rats. Hallucinogen-related TIQs lacked appreciable affinity for 5-HT2A serotonin receptors and did not produce DOM-like effects in tests of stimulus generalization in DOM-trained rats. It is concluded that the phenylalkylamine conformation represented by the TIQs is not a major contributor to these actions.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1612-65-3
