The interaction of arglabin, a sesquiterpene lactone of the guaiane type, with peracetic acid and hydrogen chloride has been investigated.This led to the systhesis of nine compounds the structure of which have been established in the basis of spectral characteristics (IR, PMR, and mass spectra).The structures and absolute configurations of the molecules of 3α,10α-dichloro-1β,4β-dihydroxy- and 10α-chloro-1β-hydroxy-3β,4β-epoxyarglabins have been determined as 3R,10R-dichloro-1R,4R-dihydroxy-5S,6S,7S-trans-trans-guai-11(13)-en-6,12-olide and 10R-chloro-1R-hydroxy-3S,4R-epoxy-5S,6S,7S-trans-trans-guai-11(13)-en-6,12-olide, respectively.
