Iron-Catalysed Reductive Amination of Carbonyl Derivatives with Ω-Amino Fatty Acids to Access Cyclic Amines

An efficient method for the reductive amination of carbonyl derivatives with ω-amino fatty acids catalysed by an iron complex Fe(CO)4(IMes) [IMes=1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene] by means of hydrosilylation was developed. A variety of pyrrolidines, piperidines and azepanes were selectively synthesised in moderate-to-excellent yields (36 examples, 47–97 % isolated yield) with a good functional group tolerance.

Iron-catalyzed intermolecular hydroamination of styrenes

An iron-catalyzed formal hydroamination of alkenes has been developed. It features O-benzoyl-N,N-dialkylhydroxylamines as the electrophilic nitrogen source and cyclopentylmagnesium bromide as the reducing agent for intermolecular hydroamination of styrene

Copper-catalyzed intermolecular regioselective hydroamination of styrenes with polymethylhydrosiloxane and hydroxylamines

Playing Reversi with H and N: A copper-catalyzed intermolecular regioselective hydroamination of styrenes with polymethylhydrosiloxane and hydroxylamine derivatives has been developed. The catalysis accommodates challenging β-substituted substrates. Moreover, the chiral biphosphine-ligated copper complex successfully forms benzylamines with good enantiomeric ratios. Copyright

Borrowing hydrogen methodology for amine synthesis under solvent-free microwave conditions

Application of microwave heating to the Borrowing Hydrogen strategy to form C-N bonds from alcohols and amines is presented, removing the need for solvent and reducing the reaction times while still yielding results comparable with those using thermal heating.

Borrowing hydrogen in water and ionic liquids: Iridium-catalyzed alkylation of amines with alcohols

The use of [Cp*IrI2]2 as an efficient catalyst for the alkylation of amines by alcohols in either water or ionic liquid is described. Primary amines are converted into secondary amines, and secondary amines into tertiary amines in the absence of base, and the chemistry has been applied to the synthesis of the analgesic fentanyl. The conversion of primary amines into N-heterocycles by the reaction with diols is also described, along with the N-alkylation of sulfonamides.

Ruthenium-catalyzed /V-alkylation of amines and sulfonamides using borrowing hydrogen methodology

The alkylation of amines by alcohols has been achieved using 0.5 mol percent [Ru(p-cymene)CI2]2 with the bidentate phosphines dppf or DPEphos as the catalyst. Primary amines have been converted into secondary amines, and secondary amines into tertiary amines, including the syntheses of Piribedil, Tripelennamine, and Chlorpheniramine. A/-Heterocyclization reactions of primary amines are reported, as well as alkylation reactions of primary sulfonamides. Secondary alcohols requiremore forcing conditions than primary alcohols but are still effective a lkylating agents in the presence of this catalyst.

Synthesis of medium and large cyclic amines in rhodium-catalysed reactions of aminoalkenes with H2/CO1

Rhodium-catalysed reactions of N-benzyl- or N-alkyl-aminoalkenes (6) with H2/CO can give cyclic amines (7) (7-13 ring size) in good to excellent yields when BIPHEPHOS is used as a ligand. Hydrogenation of the aminoalkene becomes a competing reaction for the smaller rings but can be overcome by using a H2/CO gas ratio of 1:5. Reactions of 2-alkenyloxybenzylamines (13) gave 9-, 12- and 17-membered rings (14) in 30-40% yield, but dimer formation (16) and/or hydrogenation were competing reactions. Similar reactions of alkenylamides and ortho-alkenylanilines gave only non-cyclized amino aldehydes as products in low isolated yields.

A direct route to medium and large cyclic amines from aminoalkenes

Rhodium-catalysed reactions of aminoalkenes with H2/CO give cyclic amines with a range of medium and large ring sizes in yields up to 85%. High regioselectivity for non-branched products can be obtained when BIPHEPHOS is used as a ligand in the

A New and Convenient Synthesis of N-Substituted Perhydroazepines from Adipaldehyde and Primary Amines with Tetracarbonylhydridoferrate, HFe(CO)4-, as a Selective Reducing Agent

Ethanolic tetracarbonylhydridoferrate combined with adipaldehyde is very efficient for the selective transformation of an amino group into perhydroazepine.A large variety of both aliphatic and aromatic amines react with adipaldehyde in the presence of tetracarbonylhydridoferrate at room temperature and carbon monoxide to give the corresponding N-alkyl- and N-arylperhydroazepines in good to excellent yields.
