  A novel ynamide-mediated thioester synthesis strategy was developed. Importantly, no detectable racemization was observed for the thioesterifications of carboxylic acids containing an α-chiral center, enabling it to be useful for the synthesis of peptide thioester, which is the key component of native chemical ligation. It is worth mentioning that amino acid side chain functional groups such as -OH

  开发了一种新的 ynamide 介导的硫酯合成策略。重要的是，对于含有 α-手性中心的羧酸的硫酯化，没有观察到可检测到的外消旋化，这使其可用于合成肽硫酯，这是天然化学连接的关键成分。值得一提的是，-OH和吲哚-NH等氨基酸侧链官能团与反应条件相容，无需对其进行保护。此外，这种方法也适用于硒代酯。

  It was found that sodium salt of 1,2-benzisothiazole-3(2H)-thione 1,1-dioxide (thiosaccharin) readily reacted with alkyl halide affording 3-(alkylthio)-1,2-benzisothiazole 1,1-dioxide (3). Treatment of 3 with piperidine produces the corresponding alkanethiol in situ quantitatively and subsequent treatment with various electrophiles gives the corresponding sulfides and thiocarboxylic S-esters in good yields.

  An efficient method for targeting a variety of symmetrical and asymmetrical α-substituted dithiomalonates (DTMs) is described, utilizing 1H-imidazole-1-carbothioates as reactive acylating agents and MgBr2⋅OEt2/DBU or LiHMDS for soft or hard enolization conditions of thioesters, respectively. The utility of this methodology was demonstrated through the synthesis of the pyridopyrimidine mesoionic insecticides:
