Carbonyl protection: This work highlights the potential of arylazo sulfones as non-ionic photoacid generators (PAGs) to promote the efficient conversion of aldehydes and ketones into acetals, ketals, and 1,3-oxazolidines upon visible-light irradiation. This approach takes advantage of the mild conditions employed and exhibits an easy scalability and a broad substrate scope (80 examples included).
羰基保护:这项工作强调了芳基偶氮砜作为非离子光致产酸剂 (PAG) 在可见光照射下促进醛和酮有效转化为缩醛、缩酮和 1,3-恶唑烷的潜力。这种方法利用了所采用的温和条件,并表现出易于扩展和广泛的底物范围(包括 80 个示例)。
