Protecting-group effect

A general trend in protecting group effects exists. For galactose, the most thoroughly explored series of donors, we find that the substituent plays a significant... [Pg.229]

Fiirstner et al. reported the same protecting-group effect using complex GN, with the free phenol 79 exclusively furnishing Z-80 (Scheme 2.31) [53]. They ruled out the interaction of the free phenol with the catalyst, and proved by semi-empirical calculations that there is no correlation between the E/Z ratios and the thermodynamic stabilities of the products, so this effect remains unexplained. The first-generation catalyst Gl is unable to react with the trisubstituted olefin at CIO. [Pg.53]
