In the presence of titanium (IV)tert-butoxide, the title 3-acetoxyaminoquinazolinone aziridinates styrene, butadiene and indene completely diastereoselectively; the absolute configuration of the styrene-derived aziridine 6a is proven by X-ray crystallography and is consistent with a transition state model involving chelation control by titanium.
在四氟化钛(IV)叔丁醇的存在下,标题中的3-乙氧基氨基喹唑啉酮能够完全的二氟选择性地对苯乙烯、丁二烯和茚进行腈化反应;通过X射线晶体学证明了苯乙烯衍生的腈化物6a的绝对构型,并且与涉及钛的配位控制的过渡态模型一致。
