molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile

An efficient synthesis of (3′-terminally) 3′(2′)-O-aminoacylated pCpA derivatives is described, which could lead to the production of (aminoacyl)-tRNAs following T4RNA ligase mediated ligation. The tetrahydrofuranyl (thf) group was used as a permanent protective group for the 2′-OH of the cytidine moiety which can be removed during the purification of the 3′(2′)-O-aminoacylated-pCpA. This approach
