Abstract

Syn- und anti-1,2-Diole werden in Gegenwart von SiCl4 und einem chiralen Bisphosphoramid als Katalysator hoch diastereo- und enantioselektiv aus entsprechend substituierten Silylketenacetalen von Glycolaten erhalten (siehe Schema; TMS=Trimethylsilyl, TBS=tert-Butyldimethylsilyl). Die Diastereoselektivität kann umgekehrt werden, indem man die Größe der Substituenten an den Silylketenacetalen verändert.
