Sulfur-containing natural products are ubiquitous in nature, their most abundant source being marine organisms since sulfur, in the form of the sulfate ion, is the second most abundant anion in sea water after chloride. As part of natural products, sulfur can appear in a multitude of combinations and oxidation states: thiol, sulfide (acyclic or heterocyclic), disulfide, sulfoxide, sulfonate, thioaminal, hemithioacetal, various thioesters, thiocarbamate and isothiocyanate. This review article focuses on β-hydroxy sulfides and analogs; their presence in natural products, general protocols for their synthesis, and examples of their application in target oriented synthesis.
含硫天然产物在自然界中普遍存在,其最丰富的来源是海洋生物,因为硫酸根离子形式的硫是海水中仅次于氯离子的第二丰富阴离子。作为天然产物的一部分,硫可以以多种组合和氧化态出现:硫醇、硫化物(无环或杂环)、二硫化物、亚砜、磺酸盐、硫代缩醛胺、半硫代乙缩醛、各种硫酯、硫代氨基甲酸盐和异硫氰酸酯。这篇综述文章重点关注β-羟基硫化物及其类似物;它们在天然产物中的存在、合成的一般方法以及它们在目标导向合成中的应用实例。
