[3+2]-Dipolar Cycloaddition of Aldehyde-Tethered Alkynamides and Trimethylsilyl Amino Esters: A Gateway to Uniquely Functionalized Polycyclic N-Heterocycles via Post-Ugi Functionalization
An efficient method for the generation of uniquely functionalized pyrrolo-pyrrolizinones, pyrido-pyrrolizinones, and azepino-pyrrolizinones via [3 + 2]-dipolar cycloaddition is described. The method involves the synthesis of tethered alkynamides using Ugi condensation and oxidation that were subsequently subjected to a dipolar cycloaddition reaction with trimethylsilyl amino esters. Further transformations to demonstrate the utility of these scaffolds were also investigated.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 1117-71-1. Recommanded Product: 1117-71-1.
