Synthesis of mercaptaryl or hydroxyaryl enol ether alkali metal salts

摘要

Hydroxyaryl enol ether alkali metal salts having the formula: ##STR1## in which T is a fused, substituted or unsubstituted polycycloalkylidene group, OR.sup.3 is an ether group Y is a light- emitting fluorophore- forming group which will be part of a luminescent substance formed by decomposition of a 1,2-dioxetane subsequently formed from the hydroxyaryl enol ether alkali metal salt, capable of absorbing energy to form an excited state from which it emits optically detectable energy to return to its ground state, and AM.sup.30 is an alkali metal cation, processes for the preparation of these intermediate salts, and their use as starting materials for acylation, phosphorylation and glycosylation reactions to give intermediates reactable to give stable, water-soluble chemiluminescent 1,2-dioketames, particularly ones that are enzymatically cleavable, are disclosed.
