  A novel dipeptide, N-γ-glutamyl boletine, and a cyclic iminium toxin from the mushroom Tylopilus sp. (Boletaceae)

  摘要：

  N-gamma-Glutamyl boletine and a toxin, 2-buty1-1-azacyclohexene iminium salt, were isolated from the mushroom Tylopilus sp. (Boltaceae). The absolute stereostructure of N-gamma-glutamyl boletine was clarified based on spectroscopic analysis, acidic hydrolysis and total synthesis. N-gamma-Glutamyl boletine exhibited moderate antibacterial activity. 2-Buty1-1-azacyclohexene iminium salt exhibited moderate acute toxicity against ddY mice. We proposed feasible biosynthetic pathway of piperidine alkaloids that the cyclic imimum compound might be biosynthesized from boletine, a new amino acid containing an delta-amino ketone moiety.

• Diastereotopos-differentiating allylic alkylation as a key step in the synthesis of γ-glutamyl boletine
  作者：Dnyaneshwar Gawas、Uli Kazmaier

  DOI：10.1039/b917589j

  日期：——

  γ-glutamyl boletine is described, based on a diastereotopos-differentiating allylic alkylation of chelated amino acid ester enolates. Independent of the configuration of the leaving group in the allylic substrate, the allylation product is obtained as a single stereoisomer. Its configuration is solely controlled by the stereogenic center adjacent to the π-allyl complex formed.
