摘要:
A method of preparing optically pure (S)-3-hydroxypyrrolidine is disclosed. The present invention provides a method of economically and industrially preparing optically and chemically pure (S)-3-hydroxypyrrolidine, through a process comprising introducing an amine protecting group by using optically pure 4-amino-(S)-2-hydroxybutylic acid as a starting material, reducing a carboxylic acid group into a primary alcohol, removing the amine protecting group to form an amine salt, halogenating the primary alcohol, and amine cyclization; and through a simple purification process, i.e., distillation under reduced pressure. As another method, the present invention provides a method of preparing optically and chemically pure (S)-3-hydroxypyrrolidine, through a process comprising esterifying optically pure 4-amino-(S)-2-hydroxybutylic acid as a starting material, lactam cyclization, and reduction.

摘要:
A method for preparing ketones has advantages of improving yields and reducing the time of the reactions due to high efficiency of catalysts. Ketones are prepared by reacting an aliphatic or an aromatic aldehyde with a vinyl olefin having an aliphatic or aromatic alkyl moiety in the presence of a transition metal catalyst, 2-aminopyridine catalyst, a primary amine and an acid, as catalysts and additives.
