Treatment of toyocamycin or sangivamycin with 1,3-dibromo-5,5-dimethylhydantoin in MeOH (rt/30?min) gave 8-bromotoyocamycin and 8-bromosangivamycin in good yields. Nucleophilic aromatic substitution of 8-bromotoyocamycin with sodium azide provided novel 8

A number of new nucleoside derivatives are disclosed as inhibitors of DOT1L activity. SARs established that DOT1L inhibition could be achieved through incorporation of polar groups and small heterocycles at the 5-position (5, 6, 12) or by the application of alternative nitrogenous bases (18). Based on these results, CN-SAH (19) was identified as a potent and selective inhibitor of DOT1L activity where the polar 5-nitrile group was shown by crystallography to bind in the hydrophobic pocket of DOT1L. In addition, we show that a polar nitrile group can be used as a non-traditional replacement for heavy halogen atoms.
Studies on the glycosylation of pyrrolo[2,3-d] pyrimidines with 1-O-acetyl-2,3,5-tri-O-benzoyl -β-D-ribofuranose: The formation of regioisomers during toyocamycin and 7-deazainosine syntheses

Glycosylation of silylated 4-amino-6-bromo-5-cyano-7H-pyrrolo[2,3-d] pyrimidine (9) with 1-O-acetyl-2,3,5-tri-O-benzoyl - d-ribofuranose (10) under "one-pot" glycosylation conditions (MeCN, TMSOTf) yielded the N-7 isomer 11 together with the N-1 compound 13 (ratio = 2:1). When the same conditions were applied to 4-hydroxy-7H-pyrrolo[2,3-d]pyrimidine (21) the N-3 isomer 22 was the only glycosylation product formed in almost quantitative yield.
