Evidence for an NIH Shift as the Origin of the Apparently Anomalous Distribution of Deuterium in Estragole from Artemisia dracunculus
摘要:
Feeding experiments of [2-H-2]- and [4'-H-2]phenylalanine in Artemisia dracunculus validate the hypothesis that the marked difference in deuterium content at the natural abundance level between the aromatic carbons of estragole (1) is due to an NIH shift during the hydroxylation of the benzene ring.
entirely unnatural catalytic mechanism and exhibits marked substrate generality. Taking advantage of the biorthogonality of RPDase and the geneticcode expansion method, we further demonstrated the first whole-cell photobiocatalysis using recombinant Escherichia colicells that express RPDase. Our results show that artificial enzymes bearing a synthetic organophotocatalyst is promising to generate a non-natural
