Description

General description

(+)-Dimethyl 2,3-O-isopropylidene-D-tartrate is a chiral reagent used in organic synthesis. It is prepared by the reaction-rectification process from D -tartrate, and 2,2-dimethoxypropane.{138]

Application

(+)-Dimethyl 2,3-O-isopropylidene-D-tartrate can be used as a starting material for the synthesis of:

Deuterated 1-deoxy-D-xylose.
C-terminal peptide -oxo-aldehydes using Fmoc solid-phase peptide synthesis methodology (SPPS).
Bis-Weinreb amide, a key intermediate for the preparation of myo-inositol analog via ring-closing metathesis.

Valuable building block for TADDOL chiral auxiliaries, dipyridine ligands, and threitols.
