A Stereocontrolled 1,2‐Addition Reaction of Tetrazoles with Alkyl Propiolates for the Synthesis of Highly Functionalized Enamines
A stereocontrolled 1,2‐addition reaction of 1‐aryl‐1H‐tetrazoles with alkyl propiolates for the synthesis of highly functionalized enamines was developed. In the presence of silver oxide (Ag2O), the 1,2‐addition reaction generated (Z)‐N‐cyano enamines in good yields with exclusive formation of the Z‐isomers. Meanwhile, the 1,2‐addition reaction generated (E)‐N‐cyano enamines in the presence of Ag2O and potassium carbonate (K2CO3) with high stereoselectivity and yields.
