1,3-dipolar cycloaddition reactions in the series of N-alkynyl-substituted uracils
摘要:
Reactions of 1-(omega-bromoalkyl)-3,6-dimethyluracils and 1,3-bis(omega-bromoalkyl)-6-methyluracils with sodium azide gave the corresponding mono- and bis-azides. 1,3-Dipolar cycloaddition of the latter with prop-2-yn-1-ol, hex-1-yne, and dec-1-yne in the presence of copper(I) ions afforded acyclic and macrocyclic uracil derivatives containing 1,4-disubstituted 1,2,3-triazole fragments, which were subjected to quaternization with propyl iodide and methyl p-toluenesulfonate at the 1,2,3-triazole nitrogen atom.
