Two Efficient Methods for the Conjugation of Smooth-Form Lipopolysaccharides with Probes Bearing Hydrazine or Amino Groups. II. LPS Activation with a

-4-dimethylaminopyridinium tetrafluoroborate (CDAP). The method yields conjugates with good labeling ratios, preserving the endotoxic activity of the lipid A moiety. Conjugation of smooth-form LPS from Salmonella enterica sv. Minnesota with dansyl hydrazine and horseradish

Two‐Step, One‐Pot Synthesis of Inosine, Guanosine, and 2′‐Deoxyguanosine O6‐Ethers via Intermediate O6‐(Benzotriazol‐1‐yl) Derivatives

) and Cs2 CO3 under a nitrogen atmosphere. Conversion to the O 6 ?(benzotriazol?1?yl) ethers occurs within about 10 min for inosine, and within about 60 min for guanosine and 2??deoxyguanosine. Then, for reaction with alcohols, the reaction mixture
