A new general one-pot method for high-yield synthesis of S-alkyl β-ketothioesters by heating of 6-mono- and 5, 6-disubstituted 1, 3-dioxin-4-ones and thiols in an appropriate aprotic solvent is described. This procedure is available for large-scale preparation of a variety of β-ketothioesters.
本文描述了一种新的通用一步法,通过在适当的无质子溶剂中加热6-单取代和5,6-双取代的1,3-二氧杂环-4-酮与硫醇,实现高产率合成S-烷基β-酮硫酯。该方法适用于大规模制备多种β-酮硫酯。
