Method for preparing an optically pure benzofuran carboxylic acid and use thereof for preparing efaroxan

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.

A new efficient synthesis of efaroxan

The key step of the synthesis of efaroxan was the dihydrobenzofuran ring formation involving an intramolecular cyclization of the tertiary alcohol intermediate with the fluoroaromatic moiety in basic medium. This carbinol was prepared according to two rou

α-Adrenoreceptor Reagents. 2. Effects of Modification of the 1,4-Benzodioxan Ring System on α-Adrenoreceptor Activity

Modification of the 1,4-benzodioxan ring present in RX 781094 (1) has not previously been considered.This paper describes a number of analogues of this ring system, including compounds in which one of the oxygen atoms has been replaced by a methylene group and also those in which the ring size has been changed to give, for example, furan and thiophene derivatives.The dihydroxybenzofuranylimidazoline compound 7 is the only analogue possesing presynaptic antagonist potency and selectivity comparable to that of 1.In view of this result, a number of derivatives was prepared to determine the structure-activity relationships within this series.Many derivatives, as well as the parent compound 7, were found to possess presynaptic α2-adrenoreceptor antagonist and postsynaptic α1-adrenoreceptor partial agonist properties.Two of the selective presynaptic antagonists,13 and 14, possess greater potency and selectivity than that possessed by 1.The 5-chloro derivative 25 is twice as potent as 1 after oral administration but only about half as potent when given intravenously.
