摘要:
The present invention relates to novel fluorinated benzodioxane imidazoline derivatives, to their preparation and to their therapeutic applications. The invention is directed more particularly toward the compounds corresponding to the structure of general formula 1: in which: R represents a linear, branched or cyclized alkyl or alkenyl group containing 1 to 7 carbon atoms, or a benzyl group, and the fluorine atom can occupy position 5, 6, 7 or 8, in their racemic form and their dextrorotatory and levorotatory pure enantiomeric forms, and also the addition salts thereof.
摘要:
A method for preparing an optically pure 2-ethyl-2,3-dihydrobenzofurancarboxylic acid of formula II wherein R is a hydrogen atom, halogen, lower alkyl, lower alkoxy or hydroxy is described. ##STR1## The method comprises separating the racemic mixture by selective crystallization with the suitable optically pure enantiomer of 2-phenylglycinol, in a suitable solvent, whereafter the optically pure, crystallized acid of formula II is isolated and recovered. The invention also provides the optically pure 2-ethyl-2,3-dihydro-benzofurancarboxylic acid derivative thus obtained and the use thereof for the preparation of an optically pure derivative of efaroxan.

摘要:
A signaling architecture for a cross connect switch utilizes out-of-band communications channels to transmit status information from line modules to the switch module. The out-of-band communication channels are separate from the in-band payload data connections routinely used to connect line modules to the switch module. A framer is used to extract payload data for transmission on the in-band payload data connections. The framer also extracts status information that may be encoded before sending to the switch module via the out-of-band communications channels. The switch module logically pairs STS-1s into working/protect pairs and utilizes the STS-1 granular status information to decide which of the pair is a better copy which is output as the working copy after the cross-connect switch fabric is configured according to user demands. A redundant switch module may also be used for equipment protection.
