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, 118864-75-8, name is (S)-1-Phenyl-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery. Synthetic Route of 118864-75-8
An improved process for the preparation of solifenacin succinate (1) involving resolution through diastereomeric crystallization is described. (1S)-IQL derivative (5) is esterified to form (1S)-ethoxycarbonyl IQL derivative (6) which is condensed with (RS)-3-quinuclidinol (7) to form a solifenacin diastereomeric mixture (8); this is subjected to resolution through diastereomeric crystallization to produce solifenacin succinate (1), which is used for the treatment of an overactive bladder.
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 118864-75-8
