Published: June 2011

A palladium-catalyzed decarboxylative coupling of potassium cyanoacetate with aryl bromides and chlorides is described. The reaction conditions feature the absence of additional strong inorganic bases and provide ester functional group tolerance. With Pd(dba)(2) and XPhos ligand as the catalyst system, α-diaryl nitriles can be obtained in good yields.

Optically active spirocycles were prepared in a sequence of two palladium-catalyzed reactions. In the first step, racemic α-(-iodophenyl)-β-oxo allyl esters were submitted to the palladium-catalyzed decarboxylative asymmetric allylic alkylation reaction, furnishing the α-allylated products with a quaternary stereocenter with good yields and enantioselectivities. Subsequently, these intermediate products were converted in a Heck reaction yielding the spirocyclic structures as a mixture of - and -cyclic regioisomers.

An efficient and highly regioselective palladium-catalyzed oxazoline-directed alkoxylation is reported. The reaction proceeds under air and mild temperatures (60 °C). A series of alcohols can be used as alkoxylating agents and concomitantly act as reaction solvents, whereas primary and secondary alcohols are tolerated.

The palladium-catalyzed [3 + 2] decarboxylative cycloaddition of 4-vinyl-4-butyrolactones with sulfamate-derived cyclic imines has been developed, providing the sulfamate-fused pyrrolidine derivatives in high yields with good diastereoselectivities. The scale-up reaction and further derivation of the product worked well, demonstrating the potential application of the current reaction in organic synthesis. A plausible reaction mechanism was also proposed.

A direct and convenient strategy for the assembly of indolo[1,2-]phenanthridine a Pd-catalyzed tandem cyclization reaction is presented. The current strategy delivers a range of indolo[1,2-]phenanthridine derivatives by utilizing readily available 1-(2-iodophenyl)-1-indole and commercially available -bromobenzoic acids as the starting materials. The reaction features the formation of two C-C bonds through Pd-catalyzed C-H bond activation and decarboxylation.

Palladium-Catalyzed Dearomative Heck/C(sp)-H Activation/Decarboxylative Cyclization of C2-Tethered Indoles.

Until now, palladium-catalyzed dearomative Heck reactions of indoles were largely limited to β-H elimination and nucleophilic capture of the transient alkyl-Pd(II) species. Herein, we disclose a novel palladium-catalyzed dearomative Heck/C(sp)-H activation/decarboxylative cyclization of C2-tethered indoles. In this protocol, the alkyl-Pd(II) species formed by dearomatization of C2-tethered indoles is not terminated by common β-H elimination or nucleophilic capture, but rather generates ,-palladacycle via C-H activation.
