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。
Synthesis of <i>N</i>-unsubstituted cycloalkylimines containing a 4 to 8-membered ring
Primary cycloalkylimines with a 4 to 8-membered ring were synthesized by dehydrocyanation of the corresponding α-aminonitriles on solid potassium hydroxide via a vacuum gas–solid reaction. Imine–enaminetautomerism has been demonstrated at room temperature for the most kinetically stable derivatives.

Abstract The reaction of bromo-substituted chalcones with various diamino-compounds leads to the fused heterocyclic products, aziridinylpiperazines, exhibiting photoreactivity in the crystalline state. Crystals of 4-nitrosubstituted compounds of this family change their color from yellowish to deep violet-blue, 4-cyanosubstituted ones – from yellowish to pink at UV irradiation. Discussion on the mechanism

Multigram synthesis of (chlorosulfonyl)benzenesulfonyl fluorides is described. Selective modification of these building blocks at the sulfonyl chloride function under parallelsynthesis conditions is achieved. It is shown that the reaction scope includes the use of (hetero)aromatic and electron-poor aliphatic amines (e.g., amino nitriles). Utility of the method is demonstrated by preparation of the
