The activation of π-bonds in diynyl esters has been investigated by using soft and hard Lewis acids. In the case of the soft selenium Lewis acid PhSeCl, sequential activation of the alkyne bonds leads initially to an isocoumarin (1 equiv PhSeCl) and then to a tetracyclic conjugated structure with the isocoumarin subunit fused to a benzoselenopyran (3 equiv PhSeCl). Conversely, the reaction with the hard Lewis acidic borane B(C6F5)3 initiates a cascade reaction to yield a complex π-conjugated system containing phthalide and indene subunits. The experimental procedures, NMR data and X-ray data can be found here. Results based upon these data are published at http://doi.org/10.1002/anie.201605239
