documented here, but the reductive deprotection step is not compatible with dCTP or the bromo substituent in β,γ-CHBr-dNTP analogues. To complete assembly of the toolkit, we describe an alternative synthetic strategy featuring ethylbenzylamine or phenylglycine-derived chiral BP synthons incorporating a photolabile protecting group. After acid-catalyzed removal of the (R)-(+)-α-ethylbenzylamine auxiliary

the individual β,γ-CHF-ATP stereoisomers 12a and 12b is reported. Configurationally differing solely by the orientation of the C–F fluorine, 12a and 12b have discrete 31P (202MHz, pH 10.9, ΔδPα 6 Hz, ΔδPβ 4 Hz) and 19F NMR (470 MHz, pH 9.8, ΔδF 25 Hz) spectral signatures and exhibit a 6-fold difference in IC50 values for c-Src kinase, attributed to a unique interaction of the (S)-fluorine of bound

synthesized a series of phosphonyl analogues of MEP and evaluated their abilities to interact with IspD, both as inhibitors of the natural reaction and as antimetabolite alternative substrates that could be processed enzymatically to form stable phosphonyl analogues as potential inhibitors of downstream MEP pathway intermediates. In this compound series, the S-monofluoro MEP analogue displays the most potent
