Process for preparing 2-methyl-4-(2,2,3-trimethyl-cyclopent-3-en- 1- yl)- but-2-en-1-ol

摘要

A process to obtain 2-methyl-4-(2, 2, 3-trimethyl-cyclopent-3- en-1- yl) -but-2-en-1-ol by reacting campholene aldehyde and propionaldehyde via aldol condensation and further subjecting the resulting reaction mixture to Meerwein-Ponndorf reduction with aluminum alcoholates in the presence of a basic amine compound.
