In this study, Zn2+induced the production of two new bispyrone-type metabolites, dictyobispyrone B and E, in the cellular slime mold Dictyostelium giganteum. Their structures were proposed on the basis of spectroscopic analysis and confirmed by chemical synthesis. They possess a novel α,α-bispyrone skeleton modified with long carbon chains. Both could be formed from two different polyketide chains through a novel biosynthetic pathway. Our results indicate that cultivation of cellular slime molds in the presence of Zn2+is a useful technique for discovering other structurally unique compounds.

Asymmetric syntheses of (-)-deoxoprosophylline from chiral L-N,N-dibenzyl serine (TBDMS) aldehyde is reported. A highly diastereoselective intramolecular reductive amination of ω-oxo amino diol is a key step of the present synthesis.
