摘要：

The isolation and structural elucidation of ambiguine isonitriles A-F from the terrestrial cyanophytes Fischerella ambigua UTEX 1903, Hapalosiphon hibernicus BZ-3-1, and Westiellopsis prolifica EN-3-1 are described. The structures of A-F were determined by spectroscopic methods and confirmed for indolenine D by X-ray crystallography. The new alkaloids are characterized by an additional isoprene unit attached to C-2 of the indole moiety. In ambiguines D-F the isoprenyl substitutent is further fused to the isonitrile-bearing carbon.
