A process for producing an optically active propargyl alcohol represented by the following formula (4):
1
wherein R
1
is an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, an alklnyl group, an alkylsilyl group, an aromatic hydrocarbon group, a C2-C10 heterocyclic group having 1-3 heteroatoms or a C1-C10 alkyl group having 1-3 heteroatoms, and R
2
is an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, an alkynyl group, an alkylsilyl group, an aromatic hydrocarbon group, a C2-C10 heterocyclic group having 1-3 heteroatoms or a C1-C10 alkyl group having 1-3 heteroatoms, which comprises allowing an aldehyde compound represented by the following formula (1):
R
1
—CHO (1)
to react with an alkyne compound represented by the following formula (2):
HC≡C—R
2
(2)
in the presence of an optically active aminoalcohol and a tertiary amine and a zinc halogenated lower alkane sulfonate in an amount of less than equivalent molar base on the aldehyde compound of formula (1); without solvent or with a solvent in an amount of 10-fold by weight or less based on the aldehyde compound of formula (1); and according to the process, high volumetrically efficiency and atomic economy can be attained, the objective optically active propargyl alcohol can be obtained in a high yield and a high enatioselectivity.
