Nitronates, bicyclic trimethylsilyl

Bicyclic trimethylsilyl nitronates undergo stereoselective Henry reactions with benzalde-hyde in the presence of fluoride ion to give cyclic hemiacetals in good yield with high diastereo-selectivity (95% ds) (Eq. 3.68).110... [Pg.54]

A stereoselective Henry reaction has also been observed between bicyclic trimethylsilyl nitronates and benzaldehyde with fluoride ion as the catalyst. The reaction results in the formation in high yield of a cyclic hemiacetal (equation 20) and is highly diastereoselective (95% ds)P-... [Pg.336]
