Thioaldehydedehydropeptides (II; R3= H) related to β-lactamantibiotics have been synthesised; at room temperature these unstable compounds polymerise while at lower temperatures the thioenols are stabilised; when thioenolisation is prevented by the presence of an α-methyl substituent polymerisation is the only observable reaction.
已经合成了与β-内酰胺类抗生素有关的硫醛脱氢肽(Ⅱ; R 3= H)。这些不稳定的化合物在室温下会聚合,而在较低的温度下,硫醇则稳定下来。当通过α-甲基取代基的存在阻止硫烯醇化时,聚合是唯一可观察到的反应。
