Reductive transformations of Schiff bases in the synthesis of functionally substituted heteroaromatic amines
摘要:
Schiff bases synthesized by condensation of 5- and 6-aminoquinolines, 5-amino-2-methylquinoline, nitroanilines, and pyrimidinylaminoanilines with substituted benzaldehydes and pyridinecarbaldehydes were reduced with sodium tetrahydridoborate in acetic acid to obtain the corresponding N-aryl(hetaryl)benzylamines, N-(pyridylmethyl)anilines, and N-(1,2,3,4-tetrahydroquinolyl)benzylamine derivatives. The reduction of arylhetarylimines with hydrazine hydrate in the presence of Raney nickel involved only the azomethine C=N bond, while the nitrogen-containing heteroaromatic ring remained intact. Under analogous conditions, nitrosubstituted Schiff bases and benzyl- and pyridylmethylamines were converted into previously unknown N-(aminobenzyl)quinolinamines and aryl(pyridyl)methyl-substituted phenylenediamines.

Functionally substituted Schiffbases obtained by the condensation of nitroaniline, pyrimidinylaminoaniline, 5-aminoquinoline, 5-aminoquinaldine derivatives with 4-methylformylbenzoate were studied in the reactions of sodium borohydride with acidic activators, hydrazine hydrate in the presence of Raney nickel, Raney alloy in the presence of potassium hydroxide. By the reduction of azomethines new benzyl
