Among the methodologies of α-amino acid asymmetric synthesis, chiral auxiliary strategy received most intensive and extensive investigations.
不对称合成α-氨基酸的方法学中,手性辅基方法是较多研究和应用的领域。
On discussing some activation models of dinitrogen by the active center, FeMo cofactor of the nitrogenase based on experiments and theoretical calculations, a new activation model of dinitrogen has been suggested.
结合实验和理论计算的结果，讨论了固氮酶的活性中心铁钼辅基（ＦｅＭｏ－ｃｏ－ｆａｃｔｏｒ）对Ｎ２的各种活化方式，并在此基础上提出了一种新模型，即Ｎ２在ＦｅＭｏ－ｃｏｆａｃｔｏｒ的内部以“４Ｆｅ端基配位＋２Ｆｅ侧基配位”的方式被活化，Ｎ２的三重键完全断裂，断裂产生的两个含Ｎ的碎片分别偏向两侧的“窗口”，再在Ｈ的进攻下被还原为ＮＨ３，并分别从两侧的“窗口”离去。
Preparation of FeMo cofactors containing single and double Mo was related with basicity of N-methylformamide.
