An iridiumcatalyst enables the reductive amination of carbonylgroups with unprecedented substrate scope, selectivity, and activity using formic acid as the hydrogen source (see scheme). The catalyst system provides significant improvement over commonly used boron hydrides.

This invention is directed to benzenesulfonamide compounds, as stereoisomers, enantiomers, tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates or prodrugs thereof, for the treatment of diseases or conditions associated with voltage-gated sodium channels, such as epilepsy.
Photometric Characterization of the Reductive Amination Scope of the Imine Reductases from<i>Streptomyces tsukubaensis</i>and<i>Streptomyces ipomoeae</i>
reductive amination catalyzed by two promising imine reductases is established in a rapid photometric NADPH assay. Substrates ranging from aldehydes to ketones and from primary to secondaryamines are accepted, thus giving access to various secondary and tertiaryamine products.

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 secondaryamines, and secondaryamines into tertiaryamines 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
描述了使用[Cp * IrI 2 ] 2作为在水或离子液体中通过醇使胺烷基化的有效催化剂。在不存在碱的情况下,伯胺被转化为仲胺,仲胺被转化为叔胺,并且该化学方法已经应用于止痛药芬太尼的合成。还描述了通过与二醇反应将伯胺转化为N-杂环以及磺酰胺的N-烷基化。
