1,3-Dipolar cycloaddition of cycloimmonium salts and 4-(trimethylsilyl)-3-butyn-2-one to access new functionalized indolizines with potential cytostatic activity

Abstract

4-(Trimethylsilyl)-3-butyn-2-one is an effective dipolarophile in the [3+2] cycloaddition reaction with cycloimmonium salts to obtain bioactive non-silicon adducts, namely 1-acetylindolizines, but also trimethylsilyl-containing adducts.
