A flexible route to bioactive 6-alkyl-α-pyrones

Both 6-chloro-α-pyrones and 3-chlorobenzopyran-1-ones react with malonates followed by a double decarboalkoxylation to give the corresponding alkyl and alkenyl products.

Divergent Syntheses of (Z)-3-Alkylideneisobenzofuran-1(3 H)-ones and 1 H-Isochromen-1-ones by Copper-Catalyzed Cycloisomerization of 2-Alkynylbenzoic Acids in Ionic Liquids

The cycloisomerization of readily available 2-alkynylbenzoic acids 1 in ionic liquids (ILs) as recyclable reaction media has been studied under the catalytic action of CuCl2. With substrates bearing an aryl group on the triple bond, a mixture o

Palladium-Catalyzed Sequential Nucleophilic Addition/Oxidative Annulation of Bromoalkynes with Benzoic Acids to Construct Functionalized Isocoumarins

An efficient and robust protocol for the preparation of 3-substituted isocoumarins via palladium-catalyzed nucleophilic addition/oxidative annulation of bromoalkynes with benzoic acids has been developed. Remarkably, preliminary mechanistic studies indicated that the transformation might proceed via a stereo- and regioselective nucleophilic addition and C-H functionalization procedure.

Convenient Synthesis of 3-Glycosylated Isocoumarins

A new route for the synthesis of 3-substituted and 8-hydroxy-3-substituted isocoumarins was developed by modified Julia olefination for initial C–C bond formation between aldehydes and benzylic sulfones. Palladium-catalyzed Meinwald rearrangement was used as a key step for the obtainment of ketone intermediates, which – upon base-promoted intramolecular cyclization – afforded the desired isocoumarins. The developed method paves the way to hitherto unknown 3-glycosylisocoumarins, in general, and 3-glucosylisocoumarins, in particular, wherein the glucosyl moiety is attached to the pyrone ring of the isocoumarin framework.

Rh(III)-catalyzed oxidative coupling of benzoic acids with geminal-substituted vinyl acetates: Synthesis of 3-substituted isocoumarins

The Rh(III)-catalyzed C-H activation initiated cyclization of benzoic acids with electron-rich geminal-substituted vinyl acetates was described. The reaction was employed to prepare a range of 3-aryl and 3-alkyl substituted isocoumarins selectively.
