WebThe previously unknown N-demethylation of galanthamine 1 to norgalanthamine 3 was selectively accomplished by a non classical Polonovski reaction using iron salts. This transformation constitutes the first example of the application of the Polonovski reaction to an N-oxide of a seven membered cyclic amine. Norgalanthamine is a valuable … Web11 nov. 2024 · The laboratory of Nielsen-Buchardt carried out the protection and then the alkylation for Caa 17 and then the opposite, alkylation–protection for Aaa. 15 In a later study, the same group found that the use of benzyl chloroformate reagent gave some problems for Aaa, but the more sophisticated Rappoport's reagent (BzlOCOImEt + BF4 −) …
