Diethyl Tartrate

Introduction

Diethyl tartrate (DET) is a clear colorless slightly viscous liquid. It is the diethyl ester of tartaric acid, which is one of the most important α-hydroxy acids and originates from the chiral pool. l-DET (CAS: 87-91-2) and d-DET (CAS: 13811-71-7) are abundant and commercially available at low and moderate cost, respectively.

Diethyl tartrate has a wide range of applications in organic synthesis including precursors for chiral catalysts [¹] and auxiliaries. [²] The desired stereoselectivity is tunable upon use of the corresponding enantiomer of diethyl tartrate. It was efficiently applied as a scaffold for the enantioselective synthesis of biomolecules. [³] In addition, it has been employed as a chiral resolving reagent. [4]
