    摘要: This invention relates to processes and intermediates for the stereoselective alkylation of carbonyl groups. The invention in particular allows the stereoselective preparation of the antidepressant drug escitalopram. It has been found that boric or boronic acid derivatives are useful bridging elements for the attachment of a chiral group to a compound containing a carbonyl group to be alkylated. The said borates and boronates are thus useful in a process for the asymmetric alkylation of a carbonyl group in a compound containing a carbonyl group and an anchor group capable of reacting with a boric or boronic acid derivative. The asymmetric alkylation can be carried out by admixing the compound containing a carbonyl group to be alkylated and the anchor group capable of reacting with a boric or boronic acid derivative with a boric or boronic acid derivative, adding a chiral alcohol, and adding an organometallic compound. After the alkylation reaction, the borate and boronate can be easily removed by hydrolysis.

On the basis of the ultrasonic measuring signal, which is describable by the defined desired quantity, or the defined, desired signal form, the process variable is ascertained via a sound-entrainment method or via an echo method.

    摘要: A method for system- and/or process-monitoring in the case of an ultrasound flow measuring device having a plurality of measuring channels, wherein a medium flows though a pipeline or measuring tube in the direction of a longitudinal axis of the pipeline or measuring tube. Ultrasonic measuring signals are coupled into the pipeline or measuring tube and coupled out of the pipeline or measuring tube in such a way that they travel through the medium along different sound paths. Following passage through the pipeline or measuring tube, the ultrasonic measuring signals are detected in the individual measuring channels, wherein at least one actual quantity describing the ultrasonic measuring signal of each measuring channel is ascertained. The actual quantity is compared with a desired quantity captured under predetermined system- or process-conditions, and a report is output in the case of a difference between the ascertained, actual quantity and the captured, desired quantity.
