Dual use of propargylamine building blocks in the construction of polyheterocyclic scaffolds
摘要:
The cyclization reactions of 2-(N-propargyl)imidazole-2-yl)indoles (synthesized via the hydroamination reaction between N-propargyl indole-2-carboxamides and propargylamine) have been investigated under Lewis acid- and base-promoted conditions. The polyheterocyclic compounds thus obtained were shown to possess promising photophysical properties. (C) 2020 Elsevier Ltd. All rights reserved.
