Synthesis of Hemiaminals and Hemiaminal ethers
Unusual N-Acyl-N,O-acetals are present in a number of bioactive natural products and can act as a synthetic precursor to unstable reactive N-acylimines. Various N-acyl-N,O-acetals can be prepared under mild conditions mediated by titanium ethoxide (Ti(OEt)4). The method also offers a new strategy to make other O-alkyl-N,O-acetals.
