    Abstract: Described are a class of chemiluminescent compound characterized by the presence an aryl ester, thioester or amide of a carboxylic acid substituted heterocyclic ring that is susceptible to chemical attack (such as by oxidic attack) to dissociate the heterocyclic ring to a transient compound. The heterocyclic ring is ring carbon-bonded to the carbonyl of the ester, thioester and amide moiety and possesses a heteroatom in an oxidation state that allows chemiluminescence by dissociating a compound ("intermediate") that decays to produce chemiluminescence, at the carbon bonded to the carbonyl. The aryl ring or ring system is ring carbon-bonded to the oxygen, sulfur or nitrogen of the ester, thioester or amide, as the case may be, and contains at least three substituents on a six-member ring. The substitution on the six-member ring comprises three or more groups acting in concert to sterically and electronically hinder hydrolysis of the ester, thioester or amide linkage.

Both processes include, as key steps, the enantioselective hydrogenation of a C.dbd.C double bond and the regioselective formation of a dicarboxylic acid monoamide derivative. In one process a phenylitaconic acid derivative is asymmetrically hydrogenated to give an optically active (R)-benzylsuccinic acid which is then converted to a diester, said diester being converted to the monoamide compound of formula 1. In the second process, a phenylitaconic acid derivative is converted to its anhydride, and the anhydride is then converted to a monoamide which is then asymmetrically hydrogenated to give the compound of formula 1.

  • Patent number: 5283334
    Abstract: A chemiluminescent compound possessing an aryl ester, thioester or amide of a carboxylic acid substituted heterocyclic ring or ring system that is susceptible to chemical attack to dissociate the heterocyclic ring to a transient compound. The heterocyclic ring is ring carbon-bonded to the carbonyl of the ester, thioester or amide moiety and possesses a heteroatom in an oxidation state that allows chemiluminescence by dissociating a compound at the carbon bonded to the carbonyl that decays to produce chemiluminescence. The heterocyclic ring or ring sustem contains bonded to it through an organic moiety, a functional group that is functionally reactive with an active hydrogen containing compound. The aryl ring is a ring or ring system that is ring carbon-bonded to the oxygen, sulfur or nitrogen of the ester, thioester or amide, as the case may be, and contains substituents on a six-member ring that act to sterically and electronically hinder hydrolysis of the ester, thioester or amide linkage.
