摘要:
A novel process for the preparation of alkyl esters of dl-trans chrysanthemic acid of the formula ##STR1## wherein R is alkyl of 1 to 6 carbon atoms comprising reacting in the presence of a strong base an alkyl 4-oxo-2E-butenoate of the formula ##STR2## with at least about 2 molar equivalents of a triphenyl isopropyl phosphonium halide which uses easily accessible starting materials.
摘要:
The present invention is related to a method for making microarrays comprising the steps of: submitting the surface of a solid support to an oxidation of chemical groups present on said surface in order to allow the formation of aldehyde functions upon the surface of said solid support, covalently binding upon said aldehyde functions capture molecules designed for the detection, the identification, the quantification and/or the recovery of complementary target biological or chemical molecules of interest; said covalent binding resulting in an array comprising a density of at least 4 or more discrete regions/cm2 of solid support surface, each of said discrete surface regions being bound with a species of capture molecules.
