NaH2PO2 was found to promote reductive amination. Being nontoxic, stable, environmentally benign, and available in bulk amounts, this reducing agent showed a powerful potential to compete with classical reductants applied in the target process. An E factor of 1 was achieved for the substrate scope. Different carbonyl compounds reacted with amines under the developed conditions. The reaction demonstrated
发现NaH 2 PO 2促进还原胺化。这种还原剂无毒、稳定、对环境无害且可大量使用,显示出与目标工艺中应用的经典还原剂竞争的强大潜力。底物范围的E因子为 1。在开发的条件下,不同的羰基化合物与胺反应。该反应显示出与多种官能团的良好相容性。反应条件放大至 200 倍。
