An approach to the total synthesis of the ionophore antibiotic tetronasin (1) is reported, in which the key step is a novel base catalysed cascade cyslisation of an activated polyene (2). This establishes two rings and four stereogenic centres in one step. A related polyene (16) has been cyclised in a similar fashion, illustrating the generality of the procedure.
