HOT: new N-spiro quaternary ammonium salt phase-transfer catalysts from tartaric acid

Mario Waser et al. have designed new N-spiro quaternary ammonium salt-based catalysts from tartaric acid-derived TADDOLs.  The new catalysts catalyse the asymmetric α-alkylation of glycine Schiff bases in good yields and up to 93% ee.
