摘要

Intermolecular hydroamination of heteroatom-substituted allenes with a bulky arylamine was carried out using a bis (amidate) bis (amido) titanium (IV) complex (1) as a precatalyst. The reaction of 2, 6-dimethylaniline with oxygen-substituted allene 2c or 2d in the presence of complex 1 gives the ketimine regioisomer as the exclusive product. Reduction of such ketimine products resulted in the formation of amino ethers that were further employed as ...
