资源简介：
The
first highly diastereo- and enantioselective synthesis of bridged O,O-acetals embedded with spirooxindoles
has been developed. Dioxindoles and 2-hydroxy cinnamaldehydes were
employed as the reaction partners in this method. The desired products
were obtained via diaryl prolinol TBS ether catalyzed Michael reaction
followed by acetal formation with TFA.
