Photolysis of the O-acyl thiohydroxamate (2), precursor to the (Z)-cyclo-oct-4-enylradical, in the presence of 18O2 and a tertiary thiol provides the labelled hydroperoxide (8). The parent (Z)-cyclo-oct-4-enylradical is shown to undergo transannular cyclization only under relatively forcing conditions.
(Z)-环-辛-4-烯基自由基的前体O-酰基硫代异羟肟酸酯(2)在18 O 2和叔硫醇的存在下进行光解,得到标记的氢过氧化物(8)。母体(Z)-环-辛-4-烯基仅在相对强迫的条件下才经历环环化。
