decarboxylation of α-alkoxy β-phenylthio acids via the corresponding Barton esters. The phenylthio acids were usually made by the known regioselective reaction of α,β-epoxy acids with PhSH in the presence of InCl3, followed by O-alkylation of the resulting alcohol. In one case, thiol addition to an α,β-unsaturated ethoxymethyl ester was used.
烯醇醚是通过相应的巴顿酯使α-烷氧基β-苯硫基酸自由基脱羧而形成的。苯硫酸通常是通过在InCl3存在下,α,β-环氧酸与PhSH的区域选择性反应制得的,然后对所得的醇进行O-烷基化。在一种情况下,使用硫醇加到α,β-不饱和乙氧基甲基酯中。
