A Highly Selective Cascade Approach to Diverse Aromatic Ring Systems from Simple Aromatic Aldehydes and Propiolates Yan-Guang Wang Sun-Liang Cui Xu-Feng Lin 10.1021/ol060143b.s003 https://acs.figshare.com/articles/journal_contribution/A_Highly_Selective_Cascade_Approach_to_Diverse_Aromatic_Ring_Systems_from_Simple_Aromatic_Aldehydes_and_Propiolates/3233155 A new triethylamine-catalyzed cascade reaction of aromatic aldehydes with propiolates has been developed. This serial multi-bond-forming process furnishes diverse polycyclic aromatic hydrocarbons, including naphthalenes, phenanthrenes, benzofurans, and 2,3,9,9a-tetrahydronaphtha[2,3-b]furans. The chemical outcome of the process depends on the reaction temperature and can be tailored selectively by an appropriate choice of experimental conditions. 2006-03-16 00:00:00 Simple Aromatic Aldehydes hydrocarbon Propiolate aldehyde phenanthrene propiolate benzofuran polycyclic reaction temperature chemical outcome Selective Cascade Approach choice naphthalene Diverse Aromatic Ring Systems cascade
