A Cu(0)/Selectfluor system-catalyzed intramolecular C-sp2-H/C-sp2-H bond cross-dehydrogenative coupling of 2-aryloxybenzaldehydes is described. A variety of substituted xanthone derivatives are synthesized in moderate to excellent yields. Reaction can also be extended to the synthesis of 9H-thioxanthen-9-one 10,10-dioxide and phenanthridin-6(5H)-ones, respectively. (C) 2019 Elsevier Ltd. All rights reserved.

An effective Pd-catalyzedregioselectivehydroesterification of 1,3-conjugated enynes with aryl formates was developed. Under the Pd–CyDPEphos catalytic system, the conjugated enynes reacted with phenyl formates and selectively provided the 2-ester-substituted 1,3-dienes in good yields with excellent regioselectivities.

Enediyne compounds of the formula: (1) characterized in that the structure thereof is very simple and the production process is easy, and that the molecular length thereof is shorter than those of compounds having been proposed. Consequently, electrode assemblies comprising any of these enediyne compounds are highly promising in the application to nanomolecular wiring (nanomolecular wire) whose production has been difficult.
