A simple and efficient Se-radical triggered cyclization/substitution cascade reaction of alkyne-tethered cyclohexadienones to afford 5-hydroxy-3-selenyl-4a,8a-dihydro-2 H -chromen-6(5 H )-ones has been developed. This transformation via the 3,5-diselenyl-4a,8a-dihydro-2 H -chromen-6(5 H )-one interm...
