(R)-(+)-2-Methyl-CBS-oxazaborolidine

CAS: 112022-83-0

(R)-(+)-2-Methyl-CBS-oxazaborolidine is a dpp-iv inhibitor that is a β-unsaturated ketone. It has been shown to inhibit the enzyme histone lysine demethylase, which may be involved in the regulation of bone mass. This compound also has a pharmacokinetic profile that is characterized by high oral bioavailability, low plasma protein binding, and rapid metabolism by liver enzymes. The reaction mechanism for this compound is based on the formation of an enolate carbanion. (R)-(+)-2-Methyl-CBS-oxazaborolidine can be synthesized with high stereoselectivity and yields from reactions with simple starting materials. This synthetic route also has a number of advantages over other methods: it does not require any protecting groups, it does not use toxic solvents such as dichloromethane or chloroform, and it can be performed in anhydrous conditions
