日期:——
A novel method for the synthesis of chiral β3-amino acids is developed where the acid functionality was built by oxidative cleavage of an α-allylic group that was introduced by Evans’ asymmetric alkylation of an appropriate acid substrate and the amino part came from the amide of the original carboxyl group following a modified Hofmann rearrangement reaction.

Provided is an alcohol production method comprising the step of reducing an ester or a lactone with hydrogen to produce a corresponding alcohol without addition of a base compound by using, as a catalyst, a ruthenium complex represented by the following general formula (1):
RuH(X)(L
1
)(L
2
)
n
(1)
wherein
X represents a monovalent anionic ligand,
L
1
represents a tetradentate ligand having at least one coordinating phosphino group and at least one coordinating amino group or a bidentate aminophosphine ligand having one coordinating phosphino group and one coordinating amino group, and
L
2
represents a bidentate aminophosphine ligand having one coordinating phosphino group and one coordinating amino group, provided that
n is 0 when L
1
is the tetradentate ligand, and n is 1 when L
1
is the bidentate aminophosphine ligand.
