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.
固氮酶单、双钼铁钼辅基的制备与N-甲基甲酰胺碱度有关。
