Disclosed are novel compounds and a method of treating a disease associated with aberrant leukocyte recruitment and/or activation. The method comprises administering to a subject in need an effective amount of a compound represented by:
or physiologically acceptable salt thereof.
carboxylation reaction of allylicC−H bonds of simple alkenes with CO2 is prompted by means of a ketone and a copper complex. The unique carboxylation reaction proceeds through a sequence of an endergonic photoreaction of ketones with alkenes forming homoallyl alcohol intermediates and a thermal copper‐catalyzed allyl transfer reaction from the homoallyl alcohols to CO2 through C−C bond cleavage.

can be achieved by using allylicalcohols directly in the presence of palladium complexes and CO2. Direct carbonylation of allylicalcohols into unsaturated carboxylic acids can be catalyzed by palladium complexes under the pressure of CO and CO2. Disproportionation of diallylamine into triallylamine and allylamine is also catalyzed by palladium complexes in the presence of CO2. On the basis of studies
通过在 CO2 下进行反应,钯配合物催化的烯丙醇中 C-O 键的直接活化得到了加速。与二乙胺反应,在常压二氧化碳和常压下,在钯配合物存在下,烯丙醇可转化为N,N-二乙基烯丙胺。在钯配合物和 CO2 存在下,直接使用烯丙醇可以实现各种碳亲核试剂的烯丙基化,例如 β-酮酯和 β-二酮。在CO和CO2的压力下,钯配合物可以催化烯丙醇直接羰基化为不饱和羧酸。二烯丙胺歧化成三烯丙胺和烯丙胺也在 CO2 存在下由钯配合物催化。

3-Substituted but-3-enoic acids were obtained in good yields under mild experimental conditions by palladium-catalyzed cross-coupling of 3-iodobut-3-enoic acid with organozinc or organotin compounds using PdCl2(MeCN)(2) as catalyst and DMF as solvent.
