Nucleotide derivatives of formula (1) are described: wherein: G is a hydrogen atom or an optionally substituted aliphatic, heteroaliphatic, cycloaliphatic, polycycloaliphatic, aromatic or heteroaromatic group or a non-natural nucleoside as defined herein; G′ is a non-natural necleoside as defined herein; n is zero, or the integer 1 or 2; m is zero or the integer 1 or 2; and the salts, solvates, hydrates and N-oxides thereof. The compounds are P2Y receptor agonists and are of use in the prophylaxis and treatment of diseases and disorders involving abnormal secretory mechanisms such as inadequate functioning of mucociliary clearance mechanisms or abnormal tear secretion or in the treatment of diseases involving inappropriate cellular glucose uptake.
An efficient and straightforward strategy for the synthesis of isoquinolones through [4 + 2]-annulation of N-chlorobenzamides with vinyl acetate in the presence of CoCp*(III) catalyst in a regioselective manner is described. Furthermore, the annulation reaction was diversified by using vinyl ketones. By utilizing this strategy, biologically valuable isoquinolone derivatives were prepared in good yields
