Synthesis of aminoisoquinolines via Rh-catalyzed [4 + 2] annulation of benzamidamides with vinylene carbonate

A new strategy is developed for the synthesis of 1-aminoisoquinoline derivatives. This Rh(III)-catalyzed [4 + 2] annulation reaction employs benzamidines as efficient directing groups and the vinylene carbonate as an acetylene surrogate. Additionally, the reaction features broad substrate scopes and good yields, only producing carbonate anion as byproduct.

Transition-Metal-Free Synthesis of 1,2-diphenyl-1H-benzo[d] Imidazole Derivatives from N-phenylbenzimidamides and Cyclohexanones

A transition-metal-free strategy for the formation of 1,2-diphenyl-1H-benzo[d] imidazoles from N-phenylbenzimidamides and cyclohexanones is introduced. This is the first report on the direct synthesis of 1,2-diphenyl-1H-benzo[d] imidazoles from cyclohexanones and N-phenylbenzimidamides via iodine- promoted oxidative cyclization. Non-aromatic cyclohexanones were smoothly dehydrogenated, and acted as an aryl source using oxygen as a green oxidant. The catalytic use of iodine makes this method quite simple, more economical and convenient. Under optimized conditions, various substituted 1,2-diphenyl-1H-benzo[d] imidazoles were smoothly reacted, and the desired substituted imidazoles were generated with moderate to excellent yields. (Figure presented.).

Metal-Free Synthesis of Polysubstituted Imidazolinone Through Cyclization of Amidines with 2-Substituted Acrylates

Polysubstituted imidazolinones were synthesized in a facile metal-free cascade nucleophilic cyclization of easily available amidines and 2-substituted acrylates. This protocol is distinguished by simple, mild, and catalyst-free reaction conditions with a broad substrate scope, affording the desired products in moderate to good yields and providing an efficient strategy for synthesis of polysubstituted imidazolinone.

Synthesis of 1,2-dihydro-1,3,5-triazine derivativesviaCu(ii)-catalyzed C(sp3)-H activation ofN,N-dimethylethanolamine with amidines

1,2-Dihydro-1,3,5-triazines and symmetrical 1,3,5-triazines were obtained in up to 81% yields from amidines andN,N-dimethylethanolamine catalyzed by CuCl2. The reaction involves three C-N bond formations during the oxidative annulation process

Metal-Free C-B Bond Cleavage: An Acid Catalyzed Three-Component Reaction Construction of Imidazole-Containing Triarylmethanes

An efficient acid-catalyzed strategy to prepare imidazole-containing triarylmethanes from amidines, ynals, and boronic acids has been developed. It represents an unprecedented and novel metal-free C-B bond cleavage strategy as a workable route to form new carbon-carbon bonds.

Transition-metal-free three-component reaction: Additive controlled synthesis of sulfonylated imidazoles

Two efficient transition-metal-free highly regioselective pathways for constructing sulfonylated imidazoles via three-component reactions of amidines, ynals, and sodium sulfonates have been developed. The generations of different sulfonylated imidazoles w

Silver-catalyzed [3 + 2] domino reaction: An efficient strategy to synthesize imidazole-5-carbaldehydes

An unprecedented regioselective silver-catalyzed [3 + 2] domino reaction of amidines and ynals for the formation of C-N bonds has been developed. The reaction provided a new route to prepare imidazole-5-carbaldehydes which are important intermediates for the construction of fine chemicals. The reaction proceeds smoothly with a broad range of substrates to give imidazoles in good yields.

Substrate-Controlled Selectivity Switch in a Three-Component Reaction: A Ag-Catalyzed Strategy for the Synthesis of Functionalized Imidazoles

An efficient Ag-catalyzed three-component reaction of amidines, ynals, and alcohols, phenols, or water has been developed. This strategy provides a wide range of substrates and represents a simple process for the preparation of different imidazole derivatives in good yields with high regioselectivities.

C-H cycloamination of N-aryl-2-aminopyridines and N-arylamidines catalyzed by an in situ generated hypervalent iodine(iii) reagent

A metal-free synthesis of diversified pyrido[1,2-a]benzimidazoles and 1H-benzo[d]imidazoles from N-aryl-2-aminopyridines and N-arylamidines has been developed. The C-H cycloamination reaction was catalyzed by hypervalent iodine(iii) species generated in situ from iodobenzene (catalytic) and peracetic acid (stoichiometric). The reaction proceeded smoothly at ambient temperature to provide the corresponding N-heterocycles in good to excellent yields.

Synthesis and structure of aroylamidines and N-arylbenzamidines hydrochlorides

Aroylamidines can be obtained as salts in a reaction of the corresponding arylcarbonitriles with anhydrous ethanol in the presence of dry HCl followed by treating intermediate imidoesters with alcoholic solution of ammonia. N-Arylbenzamidines are obtained by reacting benzonitrile with arylamines in the presence of AlCl3. The structure of arylamines and the reaction conditions signifi cantly affect the yield of the target product, and sometimes the very possibility of its preparation. Pleiades Publishing, Ltd., 2012.
