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: An improved process for the preparation of vinyl ethers by the coupling reaction of an ester of the formula ##STR1## with a carbonyl containing compound of the formula ##STR2## wherein A and R are passive organic groups and OY is a hydroxyl group or OP where P is a protecting group is described. The ester and the carbonyl containing compound are reacted in an organic solvent with a titanium salt, a metallic reducing agent and an amine base to provide the vinyl ether. The reaction is safe and produces high yields. The vinyl ethers are useful for producing dioxetanes which produce light upon triggering.

Abstract: Hydrolyzable substrates comprise blocked moieties which, when cleaved from the substrate during hydrolysis, provide electron transfer agents. The released electron transfer agents can be recycled between a reductant and a reducible compound that upon reduction provides a detectable species. Alternatively, they can be recycled between an oxidant and an oxidizable compound that upon oxidation provides a detectable species. These substrates are useful in analytical compositions, elements and methods for the determination of hydrolytic analytes, such as hydrolytic enzymes or biological cells containing such enzymes.
