Pd-Catalyzed C(sp3)–H Carbonylation of Alkylamines: A Powerful Route to γ-Lactams and γ-Amino Acids
摘要:
A novel Pd-catalyzed direct C(sp(3))-H carbonylation of alkylamines for the synthesis of gamma-lactams and gamma-amino acids has been developed, in which TEMPO was used as the crucial sole oxidant. The synthetic prospect was demonstrated by the concise total synthesis of rac-Pregbalin.
The present disclosure provides inhibitors of activin receptor-like kinase 5 (ALK5). Also disclosed are methods to modulate the activity of ALK5 and methods of treatment of disorders mediated by ALK5.

The present invention relates to a process for producing amino acid derivatives such as optically active β-amino acid in short steps with good yield and high optical purity, which comprises reacting a keto acid of the formula (1):
wherein R
1
is hydrogen, an optionally substituted hydrocarbon, etc.; R
2
is a spacer; and R
3
is an optionally substituted alkoxy, etc., or a salt thereof, with ammonia or an amine or a salt thereof in the presence of a chiral catalyst and in the presence or absence of an acid and/or a fluorine-containing alcohol, to give an amino acid derivative of the formula (2):
wherein Q is a group formed by removing one hydrogen atom from ammonia or an amine; X′ is an acid and/or a fluorine-containing alcohol; and b is 0 or 1.
