This work demonstrates diastereoselective transformations of β-ketoesters in homocamphor, implying novel synthetic pathways.
The synthesis of racemic and non-racemic homocamphor-based β-ketoester was performed in two-step sequence using AlCl₃-catalyzed Büchner–Curtius–Schlotterbeck ring expansion of racemic or R(+)-camphor. Examples of diastereoselective epimerization, alkylation, functionalization, oxidative cleavage,...
