Combination of air/moisture/ambient temperature compatible organolithium chemistry with sustainable solvents: Selective and efficient synthesis of guanidines and amidines

Highly-efficient and selective fast addition of in situ generated lithium amides [LiN(H)R] (obtained via an acid-base reaction between n-BuLi and the desired primary amine) into carbodiimides (R-NCN-R) or nitriles (R-CN) has been studied, for the first ti

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.

Intramolecular hydrogen bonding stabilizes trans-configuration in a mixed carbene/isocyanide PdII complexes

Aromatic amidines 1a-e undergo facile reaction with one isocyanide in PdCl2(CNBut)2 giving carbene complexes 2b-d (Scheme 2) in high isolated yields (79–95%). The structures of 2b–d were confirmed by the 1H and

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.

Base-Mediated Amination of Alcohols Using Amidines

Novel and efficient base-mediated N-alkylation and amidation of amidines with alcohols have been developed, which can be carried out in one-pot reaction conditions, which allows for the synthesis of a wide range of N-alkyl amines and free amides in good to excellent yields with high atom economy. In contrast to borrowing hydrogen/hydrogen autotransfer or oxidative-type N-alkylation reactions, in which alcohols are activated by transition-metal-catalyzed or oxidative aerobic dehydrogenation, the use of amidines provides an effective surrogate of amines. This circumvents the inherent necessity in N-alkylation of an oxidant or a catalyst to be stabilized by ligands.

Acid-catalyzed synthesis of imidazole derivatives via N-phenylbenzimidamides and sulfoxonium ylides cyclization

A straightforward method to synthesize imidazole derivatives from amidines and sulfoxonium ylides catalyzed by acids is reported in this study. Specifically, catalyzed by trifluoroacetic acid in DCE solvents can improve synthesis efficiency under metal-fr
