bioactive compounds. However, the atropisomerism arising from a restricted rotation around an N–N bond is largely overlooked. Here, we describe a method to access the first enantioselective synthesis of N–N biaryl atropisomers via a Cu-bisoxazoline-catalyzed Friedel–Crafts alkylation reaction. A wide range of axially chiral N–N bisazaheterocycle compounds were efficiently prepared in high yields with

Promoted by samarium in DMF, aroyl chlorides react readily with conjugated carbon–carbondoublebonds in acrylates, acrylamides, methyl vinyl ketone and styrenes in a bis-acylation manner. These reactions proceed smoothly under mild conditions without the need of pretreating or activating the metallic samarium, affording the corresponding 1,4-diketones in good to excellent yields.

functionalized 1-naphthols using alkynes and 1,3-dicarbonylcompounds by (4 + 2) annulation of C-centered radical. Electrolysis was conducted with Cp2Fe as redox catalyst, thereby eliminating the use of oxidants and transition-metal catalysts. The synthesized 1-naphthol compounds showed good antitumor activity in vitro, and further studies indicated that compound 3bl induced tumor cell apoptosis.

The ionicliquid 1-butyl-3-methyl-imidazolium hydrogen sulfate, [bmim]HSO4, efficiently catalyzes Paal–Knorr furan synthesis without any organic solvent. A wide range of aliphatic and aromatic 1,4-diketones easily undergo condensations to form furan derivatives, providing a general and convenient procedure. The Paal–Knorr reaction of ester-substituted 1,4-diketones is first reported. The ionic liquid
