Synthesis of 1-[(1,1′-biphenyl)-4-yl]naphthalene from amines obtained by the Stevens rearrangement of N-[3-(naphthalen-1-yl)prop-2-yn-1-yl]-3-phenylprop-2-en-1-aminium bromides
Metal-Free Decarboxylative Three-Component Coupling Reaction for the Synthesis of Propargylamines
摘要:
A metal-free decarboxylative three-component coupling reaction was developed. When alkynyl carboxylic acids, paraformaldehyde, and amines were reacted in CH3CN at 65 degrees C for 3 h, the desired propargylamines were obtained in good yields. This coupling reaction also showed good yield in water solvent. This reaction showed higher selectivity toward alkynyl carboxylic acids than a terminal alkyne.
Effect of substituents in the propynyl fragment and at the nitrogen atom on the intramolecular cyclization of (3-aryl-2-propynyl)-(4-hydroxy- 2-butynyl)ammonium chlorides and also on the recyclization of the products formed

l)piperazinium- and dicyclohexylammonium chlorides. In addition to the cyclization products - corresponding dialkyl(7-hydroxymethyl)naphtho[1,2-f]isoindolinium or dialkyl-(4-hydroxy-methyl)benzo[f]isoindolinium chlorides, the products of recyclization of these – dialkyl-amino-phenanthro[1,2-c]furan or dialkylaminonaphtho[1,2-c]furan are also formed. The indicated derivatives become the main products

op-2-yn-1-yl](3-phenylprop-2-en-1-yl)ammonium bromide under very mild conditions afforded potentially biologically active 4-phenyl-3a,4-dihydronaphtho[f]isoindolium salts in high yields. Some of the synthesized salts underwent cleavage on heating in aqueous alkali to give mixtures of isomeric aminomethylphenanthrenes.
