An efficient one-potsynthesis of 2H-pyranonaphthoquinone was achieved via a palladium-catalyzed C–H bondactivation/C–Cbond formation/intramolecular Tsuji–Trost reaction cascade. The unprecedented procedure exhibits excellent functional group tolerance, giving the target naphthoquinones in moderate to good isolated yields (40–88%) under mild reaction conditions. Scalable production of the product

An efficient synthesis of pyranonaphthoquinones is achieved by ethylenediamine diacetate-catalyzed reactions of 4-hydroxy-2-quinolones with a variety of α,β-unsaturated aldehydes in moderate yields. This method provides a rapid entry into biologically interesting α-lapachone derivatives with a variety of substituents on the pyran ring.

The synthesis of the biologically active alkaloid simulenoline, isolated from the roots of Zanthoxylum simulans, is reported. The natural product was assembled from simple commercial reagents via initial domino Knoevenagel/oxa-6π-electrocyclization followed by a one-pot singlet-oxygen ene-reaction/reduction sequence. New insights of singlet oxygen reactivity with olefinic substrates have been revealed
