PROCESS FOR PRODUCING AMINO ACID DERIVATIVES

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 R1 is hydrogen, an optionally substituted hydrocarbon, etc.; R2 is a spacer; and R3 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.

METHOD FOR PRODUCING AN OPTICALLY ACTIVE TETRAHYDROQUINOLINE

The present invention provides an industrially advantageous production method of optically active tetrahydroquinolines of formula (1), which comprises: 1) a step of reacting a β-ketoester of formula (2) with an amine of formula (3) to produce an enaminoester of formula (4); 2) a step of subjecting the enaminoester of formula (4) above obtained in 1) to asymmetric hydrogenation to produce an optically active β-amino acid derivative of formula (5); 3) a step of amidating the optically active β-amino acid derivative (5) above obtained in 2) to produce an amide of formula (6); 4) step of alkoxycarbonylating the amide of formula (6) above obtained in 3) to produce a compound of formula (7); and 5) a step of subjecting the compound of formula (7) above to cyclization to produce the optically active tetrahydroquinoline of formula (1).

Amine-salt-controlled, catalytic asymmetric conjugate addition of various amines and asymmetric protonation

Matrix presented. The combined use of chiral Pd complex 2 and amine salt enabled completely regulated release of free nucleophilic amine. Under these conditions, an efficient catalytic asymmetric conjugate addition of various amines was achieved to afford
