Anwendungen

It finds its applications as a reagent for Wittig olefinations with introduction of a 1,3-dioxolane moiety. It is applied as a reactant for the preparation of a ratiometric fluorescent probe for specific detection of cysteine over homocysteine and glutathione, for microwave-assisted synthesis of KN-93 as inhibitor of calmodulin kinase II, for the preparation of fluorinated spirobenzofuran piperidines as s1 receptor ligands, in the synthesis and antitumor agents, in regio-selective preparation of indole derivatives via rhodium-catalyzed domino hydroformylation/indolization.

Bemerkungen

Hygroscopic. Store away from water/moisture and oxidizing agents. Store under inert gas. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
