Abstract:
The invention relates to a method for producing compounds of the formula A1, wherein the carbon atom to which both the CF3 group and the hydroxy group are bonded is a stereocenter having either the R or the S configuration and wherein R1 and R2 are a C1-C8 alkyl, C3-C8 cycloalkyl, C2-C8 alkenyl, C4-C8 cycloalkenyl, C2-C8 alkynyl, C6-C14 aryl, or C5-C13 heteroaryl group independently of each other, wherein the alkyl, alkenyl, and alkynyl groups are straight-chained or branched and wherein all stated groups are unsubstituted or are mono- or polysubstituted with the same or different substituents selected from the group: halide, NO2, SO3H, SO3Na, SO3K, CN, OH, NH2, NH-lower alkyl, N-di-lower alkyl, COOH, COO-lower alkyl, lower alkyl, and C3-C6 cycloalkyl, and wherein terminal OH-, NH2-, and NH-lower alkyl groups and acidic H atoms are unprotected or are protected with a protective group, wherein a mixture of a zinc(II) salt, an enantiomerically pure or enantiomerically enriched auxiliary of the formula (I), wherein R3 and R4 are C6-C14 aryl, C5-C13 heteroaryl, C1-C8 alkyl, or C2-C8 alkenyl groups or hydrogen independently of each other and R5 and R6 are C6-C14 aryl, C5-C13 heteroaryl, C1-C8 alkyl, C2-C8 alkenyl, or C2-C8 alkynyl groups or hydrogen independently of each other or R5 and R6 together represent a C3-C7 alkylene or C3-C7 alkenylene group and at least one of the centers C1, C2, preferably both, is a stereocenter regardless of the configuration of the other center and has either the R or the S configuration and a second auxiliary, which is selected from the group comprising the alcohols, phenols, mercaptans, amines, carboxylic acids, urea derivatives, or the heterocycles containing nitrogen, oxygen, or sulfur, is reacted with an organic or inorganic base and then is reacted with an organometallic compound R1 -M in which R1 has the meaning specified above and in which M is selected from the group: lithium, sodium, potassium, magnesium halide, magnesium cyanide, magnesium-lower alkyl-alcoholates, and then is reacted with a trifluoromethyl ketone (II), wherein R2 has the meaning stated above.
