The Name is 3-Pyridinecarboxaldehyde. Through research, I have a further understanding and discovery of 500-22-1. Recommanded Product: 3-Pyridinecarboxaldehyde
A new strategy to 2-aminochromanes through catalyst-free cascade reaction of 3-trifluoroacetyl-4H-chromenes and 4H-chromene-3-carbaldehydes with cyclic secondary amines is presented. The reaction proceeds through subsequent 1,4- and 1,2-additions of amine, bimolecular elimination of trifluoroacetamide or formamide, and 6-exotrig cyclization. The latter stage is a very rare example of addition of phenols to enamines. The obtained semicyclic N,O-acetals were applied as useful precursors for the synthesis of other chromanes.
Recommanded Product: 3-Pyridinecarboxaldehyde. Welcome to talk about 500-22-1, If you have any questions, you can contact Osyanin, VA; Osipov, DV; Melnikova, IV; Korzhenko, KS; Semenova, IA; Klimochkin, YN or send Email.
