, p. 755 - 763 (2014)
Introduction of nitrogen substituents on a highly functionalized dihydrofuran-fused perhydrophenanthrene (DF) core was examined. Acetamide functionality could be introduced on the DF by copper-mediated Buchwald-type coupling. On the other hand, installation of free amino group on a DF was established via an aryl azide under the copper-mediated condition reported by Helquist and co-workers.
Synthesis of substituted 6H-benzo[c]chromenes: A palladium promoted ring closure of diazonium tetrafluoroborates

A highly efficient palladium-catalysed phenyl diazonium tetrafluoroborate participation of C-H activation ring closure protocol has been developed. A series of 6H-benzo[c]chromenes have been synthesized by intramolecular cyclization of ortho diazonium sal
