reagent that provides a convenient and efficient route for the synthesis of β-lactams from Schiff's bases and alkox/aryloxy acetic acids. The process involves the formation of thioester of the corresponding acid. Finally, condensation of titanium enolates, derived from these esters, with imines completes the synthesis of 2-azetidinones.
已发现 2,2'-二苯并噻唑基二硫化物是一种多功能试剂,为从席夫碱和烷氧基/芳氧基乙酸合成 β-内酰胺提供了方便有效的途径。该过程涉及形成相应酸的硫酯。最后,衍生自这些酯的钛烯醇化物与亚胺的缩合完成了 2-氮杂环丁酮的合成。
