Abstract: Preparation of O-(2-hydroxyalkyl) oximes of formula (I), (R and R are alkyl or R and R and the common C atom are 5-membered to 7-membered cycloalkyl; R is alkyl) by causing a ketoxime II to react with an olefin oxide III in the presence of a tertiary amine or with a carbonate IV in the presence of a catalyst. The end products (I) are suitable for use as intermediates for crop protection agents.

Abstract: Carboxylic esters are prepared by reacting carboxylic acids with low-boiling alcohols by charging the reaction mixture to a 1st distillation column, withdrawing the reaction components carboxylic ester, water and unconverted alcohol as overhead product and charging this overhead product to a 2nd distillation column, from which (a) the overhead product comprises the alcohol or an azeotropic mixture of alcohol and water or alcohol and esteer, this overhead product being recycled into the esterification reaction (b) a liquid side product comprising carboxylic ester and water is withdrawn from the stripping section and separated in a phase separating vessel into water and carboxylic ester and the carboxylic ester is returned into the distillation column below the side takeoff point, and (c) the bottom product removed is the carboxylic ester.

Abstract: Optically active fumaric acid diesters of the formula I in which R and R denote hydrogen or an optionally substituted alkyl, cycloalkyl, aralkyl or aryl group; R and R denote an optionally substituted alkyl, cycloalkyl, aralkyl or aryl group or the radical -CO2R , where R stands for hydrogen or a C1-C4-alkyl radical; or R is linked with R and/or R is linked with R to give a 5- or 6-membered, optionally alkyl-substituted heterocycle which can carry a further carbonyl group in the adjacent position to X or Y; X or Y stands for oxygen or the radical -NR and C denotes a centre of asymmetry of R or S absolute configuration and the preparation of the diesters I and their use as dienophiles in asymmetric Diels-Alder reactions.
