The ability to metabolically label DNA in a way that produces a latent change from one nucleobase to another would create a signal that can be amplified by PCR-this in turn would allow studies of newly synthesized DNA using high-throughput sequencing. To function as an amplifiable metabolic label, a nucleotide analogue would need to be taken up by cells and incorporated into cellular DNA; after purification of DNA, it could be converted into a different nucleobase with a different base pairing pattern. We selected 4-thiothymidine (4sT) as a candidate metabolic label: 4sT is readily taken up by a large number of polymerases in vitro, and we present a method that allows 4sT to be converted into 5-methyl-2′-deoxycytidine (5mC) after incorporation into DNA. Encouraged by these results, we treated cells with 4sT nucleoside; however, we found that 4sT is not incorporated into DNA in bacterial, yeast, or mammalian cells to useful levels under the conditions we tested. A phosphorodiamidate prodrug of 4sTMP was successfully synthesized but did not measurably improve incorporation into cellular DNA.

Asymmetric α-2-tosylethenylation of (S)-2-(pyrrolidin-1-yl)propanoic acid esters was shown to produce good yields with high enantioselectivities. The reaction proceeds via the formation of a non-racemic ammonium enolate without an external source of chirality.
