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。
Disclosed are N-derivatives of thienamycin having structures I and II. ##STR1## wherein: the bifunctional radical may contain additional unsaturation in the ring; and wherein n is an integer selected from 1-6; p is 0, 1 or 2; R.sup.1 is selected from hydrogen, alkyl having 1-6 carbon atoms, and aryl having 6-10 carbon atoms; and Z is imino (.dbd.NH), oxo (.dbd.O), hydrogen, amino, or alkyl having 1-6 carbon atoms. Such compounds and their pharmaceutically acceptable salt and ester derivatives are useful as antibiotics. Also disclosed are processes for the preparation of such compounds pharmaceutical compositions comprising such compounds and methods of treatment comprising administering such compounds and compositions when an antibiotic effect is indicated.

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
