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)
