  .alpha.-Adrenoceptor reagents. 2. Effects of modification of the 1,4-benzodioxan ring system on .alpha.-adrenoreceptor activity

  摘要：

  Modification of the 1,4-benzodioxan ring present in RX 781094 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paper describes a number of analogues of this ring system, including compounds in which one of the oxygen atoms has been replaced by a methylene group and also those in which the ring size has been changed to give, for example, furan and thiophene derivatives.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 dihydrobenzofuranylimidazoline compound 7 is the only analogue possessing presynaptic antagonist potency 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 alpha 2-adrenoreceptor antagonist and postsynaptic alpha 1-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 after oral administration but only about half as potent when given intravenously.

  A novel approach towards the preparation of racemic 1-benzyloxy-2-oxiranylmethylbenzenes using dimethyldioxirane and their hydrolytic kinetic resolution using (R,R)(Salen)Co(III)(OAc) (Jacobsen's catalyst) to afford the (R)-epoxides and (S)1,2-diols. enantioselectively, is described. The (R)-1-benzyloxy-2-oxiranylmethylbenzenes were then cyclized via an intramolecular epoxide opening reaction to give (S)-2-hydroxymethyl-2,3-dihydrobenzofurans. (c) 2005 Published by Elsevier Ltd.
