Electric Literature of 3382-18-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 3382-18-1, 6,7-Dimethoxy-3,4-dihydroisoquinoline, introducing its new discovery.
Nucleophilic Acylation of 3,4-Dihydroisoquinolinium Salts. Diastereoselective Synthesis of the Protoberberine Alkaloid (+/-)-Corydaline and of Analogous Compounds
Nucleophilic acylation of 3,4-dihydroisoquinolinium salts 3 with lithiated enol ethers 6,7, and 8 or vinyl sulfides 14 leads to the adducts 4,9, and 16, respectively, in mostly excellent yields.Hydrolysis of 4 affords 94-97percent of the ketones 5, which are transformed by treatment with conc. hydrochloric acid and successive reduction with NaH3BCN via the enamines 18 into the dibenzoquinolizidines 19, thus 5b gives (+/-)-corydaline (2 = 19b) in 84percent yield.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 3382-18-1. In my other articles, you can also check out more blogs about 3382-18-1
