Enantioselective Allylation oftert-Butyldimethylsilyl-Protected Vanillin and Synthesis of a Lignan Derivative Isolated fromMachilus wangchiana

Autor: Martin Kotora, Petr Koukal, Timothée Cadart

Publikováno v: European Journal of Organic Chemistry. 2014:7556-7560

Various enantioselective allylations and crotylations of tert-butyldimethylsilyl-protected vanillin were undertaken to assess the best methodology to provide the corresponding homoallylic alcohols in high yields with high enantiopurity. In general, m
