Generation of a Lewis acid activated formaldimine and its reaction with enol silyl ethers. N-Unsubstituted aminomethylation
摘要:
N-(Trimethylsilyl)formaldimine-AlCl3 complex 2b was generated by treating (trimethylsilyl)methyl azide with AlCl3. The reaction of 2b with various kinds of enol triisopropylsilyl ethers afforded alpha'-aminomethylated enol silyl ethers in good yields.
