An Ir-catalyzed tandem synthesis of various N-methylated tertiaryamines from three-component coupling of carbonyl compounds, amines, and methanol following reductive amination/N-methylation is reported for the first time. A wide array of substrates with tolerance of different functional groups was demonstrated. The protocol was extended to the synthesis of N-methyl containing pharmaceutically important
首次报道了还原胺化/ N-甲基化后由羰基化合物、胺和甲醇的三组分偶联合成各种N-甲基化叔胺的 Ir 催化串联合成。展示了具有不同官能团耐受性的多种底物。该方案扩展到合成含有N-甲基的药学上重要的药物分子。基于各种控制实验和不同的分析技术(如 NMR、IR 和 ESI-MS)提出了可能的催化循环。
Reductive Aminomethylation Using Ammonium Formate and Methanol as N1 and C1 Source: Direct Synthesis of Mono- and Di-Methylated Amines
single and dual reductiveamination followed by N-methylation of aldehydes and ketones to synthesize N,N-dimethyl as well as N-methyl tertiary amines, respectively, utilizing ammonium formate and methanol as N1 and C1 sources is reported. The protocol was efficiently extended to a tandem reductiveamination/N-methylation/cyclization of keto acids/esters leading to N-methyl lactams. A broad substrate
