Regio- and Stereoselective Synthesis of Spirooxindoles via Mizoroki-Heck Coupling of Aryl Iodides

A method for highly regio- and stereoselective intramolecular Mizoroki-Heck 5- exo cyclization of aryl iodides to the corresponding spirooxindoles has been developed. Electron-rich and electron-deficient aryl iodide precursors were selectively ring-closed with high stereoselectivity and good yields. The double-bond position in the cyclopentene ring was controlled by careful choice of reaction conditions. These rare spiro compounds were further functionalized to rigidified unnatural amino acid derivatives by a subsequent gas-free Pd(0)-catalyzed alkoxycarbonylation, followed by selective O – and N -deprotections.

Synthesis of 2-thio-substituted benzothiazoles via a domino condensation/S -arylation/heterocyclization process

Condensation of carbon disulfide with thiols in the presence of K 2CO3 generates carbonotrithioate salts in situ, which undergo coupling with 2-iodoanilines and subsequent intramolecular condensation and elimination under assistance of CuBr to afford 2-thio-substituted benzothiazoles. Both aliphatic and aromatic thiols are compatible with this process, delivering the corresponding heterocycles with good diversity.

Concise synthesis of optically active ring-A substituted tryptophans

A concise synthesis of optically active tryptophan derivatives was developed via diastereoselective alkylation of the Schollkopf chiral auxiliary 4 to provide alkyne 2 which underwent palladium-catalyzed heteroannulation with iodoanilines 1 to furnish protected tryptophans 3. Hydrolysis and subsequent saponification of 3 provided the desired tryptophans 12 in good yields.

A tandem “on-palladium” Heck-Jeffery amination route toward the synthesis of functionalized indole-2-carboxylates

A direct synthesis of functionalized indole-2-carboxylates involving a PdII-catalyzed annulation of ortho-iodoanilines onto a vinyl ether is described. The reaction mechanism is shown to be distinct from a stepwise Heck, intramolecular amination pathway, likely involving a tandem “on-palladium” Heck-Jeffery amination process incorporating a novel intramolecular amination step.

Pd/C-catalyzed cyclizative cross-coupling of two ortho-alkynylanilines under aerobic conditions: Synthesis of 2,3?-bisindoles

Abstract A palladium-catalyzed cyclizative cross-coupling of two o-alkynylanilines to 2,3?-bisindoles under aerobic oxidative conditions was developed. Mechanistic studies suggested that the two catalytic cycles, namely the formation of 3-alkynylindoles 8 and their subsequent cyclization to bisindoles 5, are temporally separated. The aminopalladation of 3-alkynylindoles 8 occurred only after all the N,N-dialkyl-o-alkynylanilines were consumed. The solid support (activated charcoal) played a crucial role in the second intramolecular aminopalladation process.

Cyclization of Alkyne-Azide with Isonitrile/CO via Self-Relay Rhodium Catalysis

A self-relay rhodium(I)-catalyzed cyclization of alkyne-azides with two sigma-donor/pi-acceptor ligands (isonitriles and CO) to form sequentially multiple-fused heterocycle systems via tandem nitrene transformation and aza-Pauson-Khand cyclization has been developed. In this approach, an intriguing chemoselective insertion process of isonitriles superior to CO was observed. This reaction provides an alternative strategy to synthesize functionalized pyrrolo[2,3-b]indole scaffolds.

Regiospecific, enantiospecific total synthesis of the alkoxy-substituted indole bases, 16-epi-Na-methylgardneral, 11-methoxyaffinisine, and 11-methoxymacroline as well as the indole alkaloids alstophylline and macralstonine

(matrix presented) A regiospecific, enantiospecific approach to the synthesis of ring-A-substituted indole alkaloids was developed via a doubly convergent strategy. The asymmetric Pictet-Spengler reaction and enolate-driven palladium cross-coupling processes were both executed in stereospecific fashion and served as the stereochemical basis of this approach. The synthesis of 16-epi-Na-methylgardneral (15), 11-methoxyaffinisine (16), and 11-methoxymacroline (22) has been accomplished in high yield and in enantiospecific fashion. Moreover, the key C-19 ketosarpagine system (borane adducts) 19a,b employed for the construction of 11-methoxymacroline (22) was also transformed into alstophylline 25, which resulted in completion of the total synthesis of the bisindole macralstonine (1).

Copper-catalyzed tandem reaction of 2-haloanilines with thiocarbamoyl chloride: Synthesis of 2-aminobenzothiazoles

A simple and efficient protocol for the synthesis of 2-aminobenzothiazoles by a ligand-free copper-catalyzed tandem reaction has been developed. In the presence of CuBr and t-BuOK, a variety of 2-haloanilines (halogen = Br, I) underwent the reaction with thiocarbamoyl chloride efficiently to afford the corresponding 2-aminobenzothiazoles in good yields (83?94%). The features of this method include good yield, cheap catalyst, mild reaction conditions, and broad substrate scope, which make the protocol practical and attractive in the preparation of some potential pharmaceutically active compounds.
