Double Nucleophilic Addition of Ketene Silyl (THIO)Acetals and Trimethylsilyl Cyanide to N-Allylideneamine

1 Results We have already published a double nucleophilic addition reaction of α,β-unsaturated imines with several nucleophiles such as ketene silyl acetals, trimethylsilyl cyanides, trimethylsilyl azides and thiols[1]. However, it was not easy to use N-allylideneamine 2 derived from acrolein for such reactions. Since there is no substituent at the β-position, imine 2 has high reactivity and are prone to be polymerization. We report the first synthesis of N-allylideneamines 2 using the isomerization of ...
