A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 125995-03-1, Name is Atorvastatin lactone, molecular formula is C33H33FN2O4. In a Patent，once mentioned of 125995-03-1, COA of Formula: C33H33FN2O4
PREPARATION OF AN ATORVASTATIN INTERMEDIATE
Atorvastatin lactone is prepared by hydrogenating tert-butyl isopropylidene nitrile to tert-butyl isopropylidene amine and condensing the amine with the diketone of atorvastatin to form acetonide ester. The diol protecting acetonide ester is deprotected to form a diol ester by dissolving the acetonide ester in methanol and treating with an acid. The diol ester is saponified to form a sodium salt. Methanol is removed from the reaction mixture by distillation. The sodium salt is reacidified to the free diol acid and atorvastatin lactone is formed from the diol acid. The atorvastatin lactone is directly dried without further purification.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C33H33FN2O4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 125995-03-1, in my other articles.
