  Synthesis of chiral non-racemic 3-(dioxopiperazin-2-yl)propionic acid derivatives

  摘要：

  Starting with the proteinogenic amino acid (S)-glutamate (3) a facile, high yielding synthesis of the chiral non-racemic 3-(dioxo-piperazin-2-yl)propionates 6, 11, and 14 is presented. Key intermediates in the synthesis of Ne-benzyl substituted (dioxopiperazin-2-yl)propionates 11 and 14 are the N-monobenzylglutamate 8 and the chloroacetamide 12, which allow introduction of various substituents in position 4 of the piperazine ring. In receptor binding studies with radioligands the 3-(piperazin-2-yl)propanol 15 was found to have promising affinity for sigma(1)-receptors (K-i=66.1 nM). (C) 2002 Elsevier Science Ltd.

  from (S)-glutamate, which was transformed in five reaction steps into the piperazinediones 5 bearing a propionic acid ester side chain. A two-step Dieckmann analogous cyclization provided the bicyclic ketones 7 as key intermediates. The alcohols 8 were prepared by LiAlH4 reduction of the ketones 7. NaBH4 reduction, Williamson ether synthesis and LiAlH4 reduction led to the methyl and benzyl ethers 12

  DOI：10.1021/ol990393a

  日期：2000.5.1

  Starting with the proteinogenic amino acid (S)-glutamate, a general method for the synthesis of 3-(piperazin-2-yl)propionic acid esters 7 with various substituents at N-4 of the piperazine ring system is presented. An intramolecular ester condensation of 7 is the key step in the formation of the 6,8-diazabicyclo[3.2.2]nonane derivatives 8-10, which are of interest as conformationally restricted piperazines.
