Expanding nature's catalytic repertoire to include reactions important in synthetic chemistry will open new opportunities for 'green' chemistry and biosynthesis. We demonstrate the first enzyme-catalyzed insertion of carbenoids into N-H bonds. This type of bond disconnection, which has no counterpart in nature, can be mediated by variants of the cytochrome P450 from Bacillus megaterium. The N-H insertion reaction takes place in water, provides the desired products in 26-83% yield, forms the single addition product exclusively, and does not require slow addition of the diazo component.
Selective N-alkylation of primary amines with chloroacetamides under pH-controlled aqueous conditions

A practical method for selective alkylation of primary amines with chloroacetamides under modified Finkelstein conditions using stoichiometric amounts of sodium iodide in acetonitrile/water is described. An interesting finding in this study was that α-alkylaminoacetamides are less basic than the corresponding primary alkylamines by about 2pKa units; this necessitated a pH of 12 during alkylation to optimize the monoalkylation selectivity. Depending on the amount of primary amine used, mono:dialkylation selectivities ranged from 2.7 to 10.
