A Convenient Synthesis of Triquinacene

Abstract
We have recently reported the synthesis of a derivative of triquinacene (2,3-dihydrotriquinacen-2-one (14)4) from Thiele's acid (1). Although this new synthetic route is simple in concept, it suffers from a large number of chemical steps. We wish to communicate an important overall simplification of this synthetic scheme which makes readily available triquinacene (22) and several of its derivatives.
