摘要:
AbstractThe synthesis of three analogues of 2′‐5′‐linked oligoriboadenylates is reported. Two trimers, having at the 2′‐end a 3′‐amino‐ (or 3′‐tetradecanamido)‐3′‐deoxy‐riboadenosine, were assembled via a phosphotriester approach. In the same way, we also prepared a tetramer carrying at the 2′‐end β‐L‐riboadenosine instead of β‐D‐riboadenosine. The non‐terminal building unit 3′,5′‐O‐(tetraisopropyldisiloxane‐1,3‐diyl)‐N6‐benzoyladenosine and the appropriately protected modified riboadenosines were coupled using the phosphorylating agent 2‐chlorophenyl‐O,O‐bis(1‐benzotriazolyl) phosphate. The removal of all protecting groups from the intermediate trimers and tetramer

摘要:
AbstractFive retinals, having different combinations of2H, with one having2H and13C labels at positions 11, 12, 14 and 20, were obtained with a chemical purity of above 98%, a level of2H enrichment greater than 95% and with13C enrichment of 99%. The retinals concerned are (20,20,20‐2H3)‐, (12,20,20,20‐2H4)‐, (12,14,20,20,20‐2H5)‐, (11,14‐2H2)‐, (12,14‐2H2)‐ and (12,14

摘要:
AbstractThe application of factorial designs and response surface modelling afforded specific conditions for the oxidation sulfide‐sulfoxide using calcium hypochlorite and sodium chlorite. The usefulness of these methods in synthetic chemistry is emphasize
