Treatment of
5-arylimino-4-chloro-5H-1,2,3-dithiazoles with in situ
generated (chloro)phenylketene in CH2Cl2 at rt gave
azetidin-2-one-4-spiro-5â²-(1â²,2â²,3â²-dithiazoles) as
major products, which reacted with primary and secondary alkylamines in
CH2Cl2 at rt to afford bis(2-oxo-azetidin-4-yl)
trisulfides in good to excellent yields.
将 5-芳基亚氨基-4-氯-5H-1,2,3-二噻唑与原位生成的(氯)苯基乙烯在 CH2Cl2 中于恒温条件下进行处理,得到的主要产物是氮杂环丁烷-2-酮-4-螺-5â²-(1â²,2â²,3â²-二噻唑),这些产物与伯、仲烷基胺在 CH2Cl2 中于恒温条件下进行反应,得到双(2-氧代氮杂环丁烷-4-基)三硫化物,收率良好至极佳。
