  A series of isatin-3-ylidene (6a-i) and arylthiazolyl-1,3,4-oxadiazole-2-thione derivatives 7a-i derived from arylthiazolyl carbohydrazide analogs 4a-i were synthesized. Analogously, coupling of 4f with various amino acid methyl esters in the presence of HOBt/DCC reagents afforded the carboxamide derivatives 9a-d. The newly synthesized compounds were assayed against HIV-1 and HIV-2 in MT-4 cells. All compounds are inactive, except compounds 9b and 9c which showed inhibition of HIV-1 with EC₅₀ = 2:34 μg mL^-1, and 1.12 μg mL^-1 with therapeutic indexes (SI) of 9 and <1, respectively.

  unexpected thiazole 1B formation when 2,6‐dichlorobenzothioamide 1 and ethyl bromopyruvate were reacted under basic conditions at elevated temperatures in ethanol. Thiazole 1B, regio‐isomeric to that expected under conventional Hantzsch conditions, was extensively characterized and later confirmed by single crystal X‐ray structure. We carried out this transformation with several substituted benzothioamides and

  我们观察到，在碱性条件下，在乙醇中升高的温度下，当2,6-二氯苯并硫代酰胺1与溴丙酮酸乙酯反应时，噻唑1B会意外地形成。噻唑1B与常规Hantzsch条件下预期的区域异构体具有广泛的特征，后来通过单晶X射线结构得到证实。我们用几种取代的苯并硫代酰胺进行了这种转化，发现意外的噻唑区域异构体的形成高度依赖于苯环上邻位取代基的空间位阻和电子特性。提出了一种机制来解释这种新颖的转变。
