Abstract

Examples of intramolecular cyclizations of functionalized diacetylenes are considered in the review. Cyclizations occur with the participation of one of the triple bonds that leads to ethynyl-substituted heterocycles, or of two triple bonds that is used in the synthesis of polycondensed heterocyclic systems and ensembles.
