OPTICALLY ACTIVE BISOXAZOLINE COMPOUNDS, PROCESS FOR
PRODUCTION OF THE SAME AND USE THEREOF
The present invention relates to optically active bisoxazoline compounds, process for production of the same and use thereof.
Methods for producing optically active cyclopropane compounds, which are very important compounds as synthesis intermediates of agricultural chemicals such as synthesized pyrethroid type insecticides, pharmaceuticals, etc., and whose representative example is (+)-2,2-dimethyl-3-(2- methyl-l-propenyl)cyclopropanecarboxylic acid, from prochiral olefins have been known as an asymmetric reaction using an optically active bisoxazoline compound as a ligand (e.g. JP 11-171874 A, Tetrahedron Lett., 32, 7373 (1991)).
These methods are relatively good in the diastereoselectivity (trans-isomer/cis-isomer ratio) and enantioselectivity. However, from an industrial viewpoint, it 1s desired to further improve the yield of the desired optically active cyclopropane compounds.
Disclosure of the Invention i
According to the present invention, an optically active bisoxazoline compound having naphthyl group as an asymmetric synthesis catalyst component can be easily obtained, and an optically active compound can be obtained at a high yield by using an industrially advantageous asymmetric catalyst comprising the optically active bisoxazoline compound and a copper compound.
That is, the present invention provides an optically active bisoxazoline compound represented by the formula (1):
RA RS
R! = Rr! > Lose 2
R® R® wherein R- and R? are the same, and each represents a Ci-¢ alkyl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted phenyl group, or R! and
R? are bonded each other together with the carbon atom of the oxazoline ring to which they are bonded to form a ring;
Rr? represents a substituted or unsubstituted naphthyl group (preferably a l-naphthyl group or a 2-naphthyl group); R’ and R’> are the same, and each represents a hydrogen atom or a Ci-¢ alkyl group, or R® and R® are bonded each other together with the carbon atom to which they are bonded to form a cycloalkyl ring having 3 to 6 carbon atoms; and *
represents an asymmetric center; a process for production of the same and use thereof.
Best Mode for Carrying Out the present invention
First, the optically active bisoxazoline compound represented by the formula (1) (hereinafter, simply referred to as the optically active bisoxazoline compound (1)), which is a novel compound, will be illustrated.
Examples of the C;_¢ alkyl group represented by R! and
R° include straight chain or branched alkyl groups such as a methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, n- pentyl, and n-hexyl group, and as the ring formed by bonding R' and R? each other together with the carbon atom of the oxazoline ring to which they are bonded, cycloalkyl rings having 3 to 7 carbon atoms can be exemplified.
Examples of the cycloalkyl ring include a cyclopropane ring, a cyclobutane ring, a cyclopentane ring, a cyclohexane ring, and a cycloheptane ring.
Examples of the substituted or unsubstituted phenyl group represented by R' and R? include an unsubstituted phenyl group; a phenyl group substituted with a Cj-¢ alkyl such as a 3-methylphenyl and 4-methylphenyl group; and a phenyl group substituted with a C:.¢ alkoxy group(e.g. a methoxy, ethoxy, propoxy, butoxy, pentyloxy, and hexyloxy group) such as a 2-methoxyphenyl, 3-methoxyphenyl, and 4-
methoxyphenyl group.
As the substituted or unsubstituted aralkyl group, there is, for example, a Cj;-¢ alkyl group substituted with the above substituted or unsubstituted aryl group.
Examples thereof include a benzyl, 2-methylbenzyl, 3- methylbenzyl, 4-methylbenzyl, 2-methoxybenzyl, 3- methoxybenzyl, 4-methoxybenzyl, l-naphthylmethyl, and 2- naphthylmethyl group.
In the formula representing the optically active bisoxazoline compound (1), as the substituted or unsubstituted naphthyl group represented by R>, in addition to an unsubstituted l-naphthyl or 2-naphtyl group, there are, for example, a l-naphthyl or 2-naphtyl group substituted with at least one C;_¢ alkyl or Ci.¢ alkoxy group.
Examples of the C;.¢ alkyl or Ci.¢ alkoxy group include those exemplified with respect to the substituent R!' or RZ.
Specifically, there are, for example, a 4-fluoro-l-naphthyl, 2-methyl-l-naphthyl, 4-methyl-l-naphthyl, 2-methoxy-1- naphthyl, 2-ethoxy-l-naphthyl, 4-methoxy-l-naphthyl, 2,4- dimethoxy-l-naphthyl, 2-naphthyl, 7-methyl-2-naphthyl, 1-n- propyl-2-naphthyl, 6-methoxy-2-naphthyl, and 3,8-dimethoxy- 2-naphthyl group. Among them, l-naphthyl and 2-naphthyl group are preferable.
Examples of the C:.¢ alkyl group represented by R* and
R® include a Ci.a alkyl group such as a methyl, ethyl, n-
d propyl, and isopropyl group, and a butyl, pentyl, and hexyl group. As the ring formed by bonding R! and R® each other together with the carbon atom of the oxazoline ring to which they are bonded , cycloalkyl rings having 3 to 6 carbon atoms can be exemplified. Examples of the cycloalkyl ring include a cyclopropane ring, a cyclobutane ring, a cyclopentane ring, and a cyclohexane ring.
Preferably, R* and R® represent a hydrogen atom, a Cj-3 alkyl group or a cycloalkyl ring having 3 to 6 carbon atoms formed by bonding R! and R® each other together with the carbon atom of the oxazoline ring to which they are bonded, and more preferably, they represent a C;_3 alkyl group.
In the bisoxazoline compounds represented by the formula (1), there are two asymmetric carbon atoms represented by * and the compounds wherein both asymmetric carbon atoms are (S), or (R) configurations are preferably used.
