A visible‐light‐promoted oxathiacetalization of aldehydes and ketones with 2‐mercaptoethanol and 3‐mercaptopropan‐1‐ol in the presence of eosin Y as catalyst is described leading to the formation of 1,3‐oxathiolanes and 1,3‐oxathianes at ambient temperature and under metal‐free conditions. The solvent is playing vital role in the protection of carbonyl compounds with mercaptoalcohol.
描述了在曙红Y的催化下,使用2-巯基乙醇和3-巯基丙烷-1-醇在可见光条件下促进醛和酮的乙二醛乙醛缩醛化反应,从而导致1,3-氧杂硫杂环戊烷和1,3-氧杂蒽环的形成环境温度和无金属条件下。溶剂在用巯基醇保护羰基化合物中起着至关重要的作用。
