Iron-Catalyzed Selective N-Methylation and N-Formylation of Amines with CO2

We herein describe an efficient iron-catalyzed selective N-methylation and N-formylation of amines with CO2 and silane using mono-phosphine as ligand. With commercially available [CpFe(CO)2]2 as catalyst, Fe-catalyzed methylation of amines was achieved with triphenylphosphine as a ligand. Using tributylphosphine as a ligand, Fe-catalyzed formylation of amines was realized at a lower temperature. The method was successfully applied in the late-stage methylation and formylation of drug molecules containing amine moiety. (Figure presented.).

Donor-acceptor interaction and photochemistry of polymethylene-linked bichromophores in solution

The ground-state and the excited-state spectroscopic properties of four series of polymethylene-linked anthracene-dialkylaniline bichromophores were compared as a probe to the relationship between energetics and distance in photoinduced electron transfer (PET). The results demonstrate that, when the energy level of the charge-transfer (CT) state is lowered below that of the localized excited state by appropriate substituents, there is a strong electron-donor-acceptor (EDA) interaction in the ground state which is absent in other bichromophores. Absorption and fluorescence excitation studies revealed that there is an unusually strong EDA interaction in the ground state of A-2 which is absent in other members in the A series.When A-2 is excited directly into this EDA absorption, it exhibits two CT emissions, one at 490 nm and the other at 605 nm. The quantum yield (tau(f))and the lifetime (Phi(f)) of the two emissions are dependent on the viscosity of the alkane solvent. The Phi(f) and the tau(f) of the 490 nm emission increased when the solvent viscosity was increased; however, those of the 605 nm emission remained essentially unchanged. The risetime of the 605 nm emission is 420 ps, but that of the 490 nm emission is instrument-function limiting. The results suggest that the two CT emissions may be derived from the two different conformations of the CT state. The 490 nm emission may be derived from the trans conformer of A-2, which is the major conformer at equilibrium. The EDA interaction in the trans conformer of A-2 may be treated as a type of through-sigma-bond interaction via the spacer between the n orbital of the anilino nitrogen and the pi orbital of the anthryl group. The direct excitation of A-2 from its EDA ground state to the CT state indicates that PET may occur in a sigma-linked bichromophoric system upon light absorption, thus reaching the limiting rate of a photochemical process.

PROCESS FOR PRODUCING N-METHYL OR N,N-DIMETYL AMINES

A process for producing N-methyl or N,N-dimethyl amines, which comprises using amine compound, nitro-containing compound or nitrile compound as a starting material, carbon dioxide as a methylating agent and hydrogen gas as a reducing agent, and allowing them to react in a sealed reactor for 6 to 48 h in a reaction medium at a reaction temperature of 80 to 180 C. in the presence of a composite catalyst, so as to provide N-methyl or N,N-dimethyl amines. The process of the present invention is simple and under relative mild reaction conditions. By means of the process of the invention, the target products can be prepared at low cost with a high yield. The catalysts used have a high catalytic activity and can be separated from the reaction system simply and reused.

3-(alphaR)-alpha-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl) -3-hydroxybenzyl)-N-alkyl-N-arylbenzamides: Potent, non-peptidic agonists of both the mu and delta opioid receptors

Opioid analgesics with both mu and delta opioid receptor activation represent a new approach to the treatment of severe pain with an improved safety profile. Compounds with this profile may exhibit strong analgesic properties due to mu agonism, with a reduced side effect profile resulting from delta agonism. Replacing the p-diethylamide of the known potent delta opioid receptor selective agonist BW373U86 with a m-diethylamide resulted in a compound with agonist activity at both the mu and delta opioid receptors. Modifying the amide to an N-methyl-N-phenylamide increased agonist potency at both receptors. A series of 3-(alphaR)-alpha((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl) -3-hydroxybenzyl)-N-alkyl-N-arylbenzamides have been made to explore the structure-activity relationship (SAR) around the N-methyl-N-phenylamide. Several potent agonists of both the mu and delta opioid receptors have been identified, including (+)-3-((alphaR)-alpha ((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3- hydroxybenzyl)-N-(4-flourophenyl)-N-methylbenzamide (23), which has EC50 values of 0.67 and 1.1 nM at the mu (guinea pig ileum assay) and delta (mouse vas deferens assay) opioid receptors, respectively.
