Procedure-Controlled Selective Synthesis of 5-Acyl-2-iminothlazoline and their Selenium and Tellurium Derivatives by Convergent Tandem Annulation

摘要

Convergent synthesis is of considerable importance in the construction of complex molecules, with the aim of improving the efficiency of multistep organic synthesis. Tandem annulation enables the quick and efficient construction of important cyclic compounds using common and readily available chemicals. The combination of convergent synthesis and tandem annulation not only improves step economy and operational simplicity for the synthesis of important molecules, but can also change the reaction pathway and lead to unexpected discoveries.
