Description and Uses
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.
