efficient and halogen-free catalytic methodology for the synthesis of β-amino alcohols from aromatic amines and biomass-derived carbohydrates is demonstrated for the first time. The activation of C5/C6 sugars by a ruthenium catalyst selectively generates the C2 alkylating reagent glycolaldehyde. The transformation involves metal-catalyzed hydrogen borrowing for the reduction of the imine intermediate. A series
首次证明了从芳族胺和生物质衍生的碳水化合物合成β-氨基醇的高效无卤催化方法。钌催化剂对C5 / C6糖的活化选择性地产生了C2烷基化试剂乙醇醛。该转化涉及金属催化的氢借以还原亚胺中间体。一系列带有各种取代基的芳基胺已成功地以良好或优异的产率转化为所需的产物。
