  Synthesis and .beta.-adrenergic antagonism of 2-(aryloxy)-1-(2-piperidyl)ethanols

  摘要：

  A series of erythro- and threo-2-(aryloxy)-1-(2-piperidyl)ethanol derivatives (3) was synthesized from 2-(2-oxiranyl)pyridine for evaluation as beta-antagonists. Most compounds displayed high competitive beta-blocking potency, but they lacked significant beta 1/beta 2 selectivity. The 1-naphthoxy derivative erythro-3b was 17 (beta 1) and 33 (beta 2) times more potent than its open-chain analogue, propranolol. Within the whole series, erythro-3 diastereomers were more potent beta-blockers than the threo-3 isomers, and the potency of the latter seems to be rather insensitive to structural modification. The effect of N-methylation and of interposition of an alkyl chain between the aromatic ring and the side chain, while being detrimental to beta-blocking activity, was less marked than in the classic (aryloxy)propanolamine blockers.

  The preparation and separation of diastereomeric pairs of a series of 2-aryloxy- and 2-arylalkoxy-1-(2-piperidyl)ethanols is reported. The erythro aminoalcohols were converted into threo isomers by thionyl chloride treatment of their N-acetyl derivatives and alkaline hydrolysis.
