IMPROVED ENANTIOSELECTIVE SYNTHESIS OF ANTI α-METHYL-β-HYDROXYESTERS THROUGH TiCl4-PPh3 MEDIATED ALDOL CONDENSATION
Palazzi, Camillo,Colombo, Lino,Gennari, Cesare
, p. 1735 - 1738 (2007/10/02)
The complex between TiCl4 and PPh3 effectively catalyses the aldol addition of silyl ketene acetals to aldehydes dramatically improving the anti-syn ratios.
