• A One-Pot Synthesis of 2,3-Dihydro-2-Thioxothieno[2,3-d]Thiazoles

  A variety of 3,5-disubstituted-2,3-dihydro-2-thioxothieno[2,3-d]thiazoles 3 a - h including alkyl-, aryl- and heteryl-substituents were synthesized in excellent yields in a one pot reaction between 3-substituted-5-(2-aryl (or heteryl)-2-oxoethyl)-4-oxo-2-thioxo-1,3-thiazolidines 1 a - h and either tetraphosphorous decasulfide (Method A) or Lawesson's reagent (Method B). However, fair yields of 3 were also obtained along with unknown oily products when the (E,Z)-5-(2-aryl-2-oxoethylidene) derivatives 2 f,g were similarly treated with the same reagents. Structures of products were supported by microanalytical and spectral evidence. A rationalization for the route of conversion is given.

  多种3,5-二取代-2,3-二氢-2-硫代噻吩[2,3-d]噻唑（3a-h），包括烷基、芳基和杂原子取代基，在优选的产率中通过一步反应合成了3-取代-5-(2-芳基（或杂原子）-2-氧代乙基)-4-氧代-2-硫代-1,3-噻唑烷（1a-h）与四磷酸十硫化物（方法A）或Lawesson试剂（方法B）的反应。然而，当(E,Z)-5-(2-芳基-2-氧代亚乙基)衍生物（2f,g）在与相同试剂反应时，也能得到相当产率的3以及未知油状产物。产物的结构得到了微观分析和光谱证据的支持。为转化的途径提供了合理的解释。

  4-Methoxyphenylazide cycloadds to the thiono function and undergoes nucleophilic attack at other electrophilic centers of 5-benzoylmethyl- (la) and E,Z-5-(4-bromobenzoylmethylene)- (E,2-2b) -2-thioxo-4-oxo-1,3-thiazolidines in non site selective reactions to afford variety of products. With la, the attack at the thiono as well as the hetero-ring carbonyl functions leads to the 5-benzoylmethylene-2-(4-methoxyphenylimino)- derivative (3) and the ring fission product 2-4. Similar treatment of E,Z-2b gives a mixture of the respective E,Z-2-(4-methoxyphenylimino)derivative (E,Z-5) containing 80% of the IE-configurated isomer (Z-5) and the ring enlarged thiazinonethione derivative (6), due to the attack at the thiono and exocyclic double bond functions, respectively. Rationalizations for the above mentioned conversions are given. Structures of all products are evidenced by microanalytical and spectral data,The chemistry of 4-thiazolidinones has been a subject of a series of publications(1-6) from this laboratory, Reactions of 2-thioxo-4-thiazolidinones with dipolar species in the literature are rather limited and treat the problem of alkylation of the 3-unsubstituted derivatives with diazomethane(7,8), and cycloaddition of nitrilimines to the thiono function of 5-aroylmethylene-3-phenyl-2-thioxo-4-oxo-1,3-thiazolidine(9). The present work aimed to study the reactivity of different functions in 5-alkyl- and 5-alkylidene substituted thiazolidones namely 3-phenyl-5-(2-phenyl-2-oxoethyl)-(1a) and E,Z-3-benzyl-5-(4-bromophenylmethylene)-(E,Z-2b)-4-oxo-2-thioxo-1,3-thiazolidines towards reaction with 4-methoxyphenylazide.
