Approach to extended polycyclic aromatic hydrocarbons by benzannulation and intramolecular cyclization; improvement of the reaction conditions by microwave irradiation
The extended π-conjugated compounds 1–8 were synthesized by the benzannulation of the corresponding alkyne derivatives followed by Pd-catalyzed intramolecular cyclization. For the Pd-catalyzed intramolecular cyclization, microwave irradiation reduced the amount of the Pd catalyst and the reaction time. Moreover, this protocol can be achieved to prepare the extended and twisted π-conjugated molecule 19, having anthracene, helicene, and picene skeletons.
期刊介绍：
Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry.
Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters.
Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
