approach for the efficient and highly selective synthesis of 1,2‐amino alcohols by direct reductive hydrolysis of N‐formyl‐protected α‐amino nitriles is reported. The commercially available RuHCl(CO)(PPh3)3 complex was found to be a suitable catalyst for this operationally simple protocol, in which no stoichiometric amounts of undesired metal waste are generated. The deaminative hydrogenation is performed
报道了一种通过N-甲酰基保护的α-氨基腈直接还原水解来高效,高选择性合成1,2-氨基醇的新方法。发现可商购获得的RuHCl(CO)(PPh 3)3络合物对于该操作简单的方案是合适的催化剂,其中不产生化学计量的不希望的金属废物。脱氨氢化反应在55 bar H 2下进行,使用1,4-二恶烷/水的6:1混合物作为溶剂。另外,在非常相似的条件下由氰基酮制备羟甲基醇。
