  A highly active and enantioselective titanium-catalyzed cyanation of imines at room temperature is described. The catalyst used is a partially hydrolyzed titanium alkoxide (PHTA) precatalyst together with a readily available N-salicyl-β-aminoalcohol ligand. Up to 98% ee was obtained with quantitative yields in 15 min of reaction time using 5 mol % of the catalyst. Various N-protecting groups such as

  technology was developed. The inner tube of the reactor is manufactured from a gas-permeable, hydrophobic fluoropolymer (Teflon AF-2400) membrane. HCN is formed from aqueous reagents within the inner tube and then diffuses through the membrane into an outer tubing containing organic solvent. This technique enabled the safe handling of HCN for three different organic transformations without the need for distillation

  Efficient organocatalysts for enantioselective Strecker and Mannich reactions were constructed from glucosamine as a readily accessible chiral scaffold. A variety of aromatic aldimines were subjected to hydrocyanation with good to excellent yield (72–98 %) and, in part, high enantioselectivity (69–95 % ee). Influence of the catalyst architecture on the enantioselectivity obviously arises from restrictions

  对映选择性Strecker和Mannich反应的有效有机催化剂是由氨基葡萄糖构建的，它是一种易于获得的手性支架。各种芳香醛亚胺都进行了氢氰化，收率良好至优异（72％至98％），部分对映选择性高（ee值为69％至95％）。催化剂结构对对映选择性的影响显然是由于对单糖主链的构象柔韧性施加了限制。在不对称曼尼希反应中，使用所述催化剂已经获得了中等产率（高达76％）和对映选择性（高达58％ee）。
