Description

Application

Ethyl (R)-(+)-4-chloro-3-hydroxybutyrate is a chiral building block that can be used:

• To prepare allyl stannane, a precursor for the total synthesis of macrolide iriomoteolide-1b.
• As a starting material for the synthesis of a chiral g-αmino acid fragment, which in turn is used to prepare the immunosuppressive agent FR252921.
