This paper describes an efficient scandium triflate- and triflic acid-catalyzed benzannulation of 2-(2-alkynylarylidene)-1,3-dicarbonyl compounds to afford polysubstitutednaphthalenes and benzo[a]fluorenols. The product selectivity could be tuned by subtle choice of the catalyst. An unprecedented process between alkynes and ketones is also explored.
本文介绍了一种高效的scan酸三氟甲磺酸酯和三氟甲基磺酸催化2-(2-炔基亚芳基)-1,3-二羰基化合物的联苯环化反应,以提供多取代的萘和苯并[ a ]芴醇。产物的选择性可以通过催化剂的精细选择来调节。还探索了炔烃和酮之间前所未有的过程。
