Enantiomerically pure allene-1,3-dicarboxylates were easily synthesized by using epimerization-crystallization of dissymmetric allene compounds, which were prepared from acetone-1,3-dicarboxylates and naturally abundant chiral alcohols, that is, (-)- and
Azeotropic transesterification of β-keto esters
Christoffers, Jens,Oenal, Necla

Transesterifications of methyl β-keto carboxylates catalyzed by DMAP with various high boiling alcohols can be accomplished in refluxing cyclohexane in a Dean-Stark trap. The MeOH formed is removed completely from the reaction mixture as an azeotrope lead
