The acid-and enzyme-catalysed cyclisations of a number of (Z,E)-1(10),4-cyclodecadiene derivatives were investigated. In contrast to the regular transannular C-C bond formation as observed for (E,E)-I ( I 0),4-cyclodecadiene systems, these melampolide-like systems cyclised via a number of different
