Disclosed herein are nucleosides, nucleotides and nucleotide analogs, methods of synthesizing the same and methods of treating diseases and/or conditions such as a Picornavirus and/or Flaviviridae infection with one or more nucleosides, nucleotides and nucleotide analogs.
Condensation of alkyl allyl (and 3-methyl-3-butenyl) phosphorochloridates with dialkyl phosphates gave trialkyl allyl (and 3-methyl-3-butenyl) pyrophosphates. Reactions of crotyl (2-butenyl) pyrophosphates with various nucleophiles such as phenolic ethers, aromatic amines, and nitrogen-containing heterocycles in the presence of boron trifluoride etherate gave good to moderate yields of crotylated products.

Disclosed herein are nucleosides, nucleotides and analogs thereof, pharmaceutical compositions that include one or more of nucleosides, nucleotides and analogs thereof, and methods of synthesizing the same. Also disclosed herein are methods of ameliorating and/or treating a disease and/or a condition, including an infection from a norovirus, with a nucleoside, a nucleotide and an analog thereof.
The Vilsmeier reagent derived from N-formylmorpholine produces chlorothioformates from primary and secondary alkyl xanthates. The major side products are the corresponding alkyl chlorides. Secondary alkyl chlorothioformates give lower yields due to their instability. Treating xanthates with other common chlorinating agents (oxalyl chloride, thionyl chloride) gives only dialkyl thiodicarbonates.
Renin inhibiting compounds of the formula: ##STR1## containing two .alpha.-amino acids or a single .alpha.-amino acid wherein R.sub.1 is a phosphorus containing moiety, W is oxygen or NR.sub.3 and A is a moiety selected from those of the formula: ##STR2## wherein Z is O, S, SO, SO.sub.2 and p is an integer from 1 to 2; and, when W is oxygen, A may also be a moiety of the formula ##STR3## and analogs thereof which compounds inhibit the substrate-cleaving action of renin, pharmaceutical compositions containing these compounds, processes for producing the compounds and methods of treating hypertension which employ the novel renin inhibitors.
