Prevention or therapy of inflammatory diseases caused by invasion of leukocytes such as monocytes, lymphocytes and eosinophils, by providing a substance which inhibits cell adhesion via an adhesion molecule, especially adhesion molecule VLA-4, is disclosed. A group of carboxylic acid derivatives represented by, for example,
and adhesion molecule inhibitors comprising the same as an effective ingredient were provided.
is driven by a novel activation strategy and features a unique Pd(I)-Pd(I) mechanism, involving an iodide-assisted binuclear step to release the product. This method enables β-selective hydroformylation of a large range of alkenes and alkynes, including sensitive starting materials. Its utility is demonstrated in the synthesis of antiobesity drug Rimonabant and anti-HIV agent PNU-32945. In a broader

R represents H or a mono- or poly- carboxylic acyl group;
R¹ represents H or a carboxylic ester moiety;
R² represents an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or an aralkyl group, said groups being optionally substituted, or R² represents a carboxylic ester moiety;
n = 1 - 4;
Y is O or S;
and esters thereof,
are useful as heat and photo- stabilisers for polymeric materials.
