Enzyme catalysis: Protein engineering based on iterative alanine scanning mutagenesis significantly expanded the syntheticallyuseful aromatic ketone scope of L-Bacillus cereus amine dehydrogenase. The eventual mutant (A115G/T136A/L42A/V296A/V293A) acquired after five rounds of mutagenesis successfully showed specificitytoward substrates 12 a and 13 a, which have not been reported to serve as targets

The strong boron Lewis acid B(C6F5)3 in combination with phenylsilane enables the regioselective cleavage of one out of two or three carbon–nitrogen bonds in cyclic secondary and tertiary amines, respectively. This amine deconstruction extends to large saturated nitrogen-containing heterocycles, and the functional-group tolerance is good.
强硼路易斯酸B(C 6 F 5 ) 3与苯基硅烷结合,能够分别区域选择性地裂解环状仲胺和叔胺中两个或三个碳氮键中的一个。这种胺解构扩展到大的饱和含氮杂环,并且官能团耐受性良好。
