    Abstract: PCT No. PCT/EP96/00012 Sec. 371 Date Jan. 7, 1997 Sec. 102(e) Date Jan. 7, 1997 PCT Filed Jan. 4, 1996 PCT Pub. No. WO96/22272 PCT Pub. Date Jul. 25, 1996The present invention relates to a process for the preparation of optically active 2-halopropionic acids, in which the corresponding optically active alkyl 2-halopropionates are caused to react with a carboxylic acid at elevated temperature in a transacylation reaction with the formation of the optically active 2-halopropionic acid and the alkyl carboxylate, and the optically active 2-halopropionic acid obtained is separated from the reaction mixture. The optically active products produced are important intermediates for the preparation of plant protectants and pharmaceuticals.

    Abstract: Beta-picoline derivs. (I) and their N-oxides and addn. salts are new. In (I), A = CR1R2; R1, R2 = H, 1-6C alkyl, 2-6C alkenyl or 2-6C alkynyl; or R1+R2 = 2-6C n-alkylene; B = CH2, CHOR3, CHR4 or C=NOR5; R3 = H, 1-6C alkyl, 1-6C haloalkyl, 3-8C cycloalkyl, 3-6C alkenyl, 2-6C acyl or phenyl, benzyl or benzoyl opt. mono-, di- or tri-substd. in the ring by 1-4C alkyl, 1-4C alkoxy, 1-4C haloalkyl, 1-4C haloalkoxy, halogen, cyano or nitro; R4 = H, F, Cl, Br or I; R5 = H, 1-6C alkyl, 1-6C haloalkyl, 3-7C cycloalkyl, 3-6C alkenyl or aryl-1-4C alkyl opt. mono-, di- or tri-substd. in the aryl ring by 1-4C alkyl, 1-4C alkoxy, 1-4C haloalkyl, halogen, cyano or nitro; Ar = phenyl or naphthyl opt. mono-, di- or tri-substd. by halogen, 1-6C alkyl, 1-4C alkoxy, 1-4C haloalkyl, 1-4C haloalkoxy, phenyl, phenoxy, halophenyl, halophenoxy or benzyloxy; except 1-phenyl-3-(3-pyridyl) propan-1-one (IA). The use of cpd. (IA), which is known from J. Org. Chem. 43 (1978), 3396 and Arch. Pharm. 307 (1974), 550, for the control of fungi is also claimed. Further, intermediates (II) are claimed except where A = CH2 or CH(CH3). 3 Cpds. (I), e.g., 2-ethyl-1-(4-fluorophenyl) -2-(pyridyl-3-methyl)butan-1-ol, are specifically claimed.
