Disclosed is a process of enantioselectively forming an aminoxy compound of Formula (3)
In formula (3) R
1
is one of an aliphatic group and an alicyclic group. R
2
is one of hydrogen, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group and an arylalicyclic group. R
3
is one of hydrogen, halogen, hydroxyl, and an aliphatic group with a main chain having 1 to about 10 carbon atoms. The respective aliphatic, alicyclic, aromatic, arylaliphatic or arylalicyclic groups of R
1
, R
2
, and R
3
comprise 0 to about 3 heteroatoms independently selected from the group consisting of N, O, S, Se and Si. The process includes contacting a carbonyl compound of Formula (1)
and a nitroso compound of Formula (2)
in the presence of a chiral catalyst. The chiral catalyst is a compound of Formula (IX)
公开了一种对映选择性地形成公式(3)的氨氧化合物的过程。在公式(3)中,R1是脂肪基和脂环基之一。R2是氢,脂肪基,脂环基,芳香基,芳基脂基,芳基环脂基之一。R3是氢,卤素,羟基和具有1至约10个碳原子主链的脂肪基之一。R1,R2和R3的各自脂肪,脂环,芳香,芳基脂基或芳基环脂基包括0至约3个独立选择的异原子,所述异原子选自N,O,S,Se和Si的群。该过程包括在手性催化剂的存在下接触公式(1)的羰基化合物和公式(2)的亚硝基化合物。手性催化剂是公式(IX)的化合物。
