摘要：

Reaction of Ti(OEt)(4) with lysine results in the formation of Ti(OEt)(3)(lysinate), as previously reported. Contrary to that, Al((OBu)-Bu-s)(3) only catalyzes the formation of 3-aminocaprolactam, and no substitution product was observed. The reaction of Zr(OBu)(4) with lysine at room temperature produced both 3-aminocaprolactam and Zr(OBu)(3)(lysinate); the lysinate complex was not observed when the reaction was performed at elevated temperatures.
