Also, compounds having the formula ##STR5## are produced by reacting a compound of the formula ##STR6## with a tetra-O-acylated-O-hexopyranoside halide, then hydrolyzing off the protective acyl groups.

Abstract: A novel synthesis of 1,2-dioxetane phosphate alkali metal salts and novel intermediates employed in this synthesis are disclosed. A hydroxyaryl enol ether alkali metal salt having the formula: ##STR1## wherein T can be an unsubstituted or substituted adamant-2'-ylidene group, R.sup.3 can be a methyl group, Y can be a phenyl group and M.sup.+ can be a sodium cation, is reacted with a phosphorohalidate to give the corresponding enol ether ethylene phosphate, which is then reacted with an alkali metal cyanide to give the corresponding enol ether cyanoethyl phosphate diester alkali metal salt intermediate. Singlet oxygen addition to this enol ether cyanoethyl phosphate diester alkali metal salt intermediate to give the corresponding 1,2-dioxetane cyanoethyl phosphate diester alkali metal salt, followed by .beta.-elimination of the cyanoethyl group using an alkali metal hydroxide or the like, gives the corresponding 1,2-dioxetane phosphate alkali metal salt.

Abstract: Chemiluminescent bioassays for the presence or concentration of an analyte in a sample use 1,2-dioxetanes as substrates for the enzyme of an enzyme complex that bind to the analyte. The chemiluminescence obtained from the decomposition of the dioxetane triggered by the enzyme through the formation of the corresponding 1,2-dioxetane oxyanion of the enzyme complex is enhanced by the addition of TBQ as an enhancement agent. Other polymeric quaternary onium salts can be used as enhancement agents in conjunction with enhancement additives which improve the ability of the enhancement agent to form hydrophobic regions in the aqueous sample, in which regions the 1,2-dioxetane oxyanion and its chemiluminescent decomposition products can be sequestered. A kit for performing such assays is also provided.

Abstract: Water soluble naturally-occurring and synthetic enhancer substances, generally macromolecular in nature, for example globular proteins that include hydrophobic regions such as bovine serum albumin, and polymeric quaternary ammonium salts such as poly(vinylbenzyltrimethylammonium chloride), which have the ability to inhibit light-emitting fluorophores resulting from the decomposition of chemiluminescent compounds from releasing energy through non-light emitting pathways, are disclosed as permitting the stabilization, and hence increasing the light intensity, of such light-emitting fluorophores in aqueous media as compared to the intensity of the light emitted by the same quantities of such fluorophores in aqueous media in the absence of such enhancer substances. Any chemiluminescent enzymatically cleavable 1,2-dioxetane, for example 3-(2'-spiroadamantane)-4-methoxy-(3"-phosphoryloxy)phenyl-1,2-dioxetane disodium salt, can be used.
