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

A new one-step synthesis of allene-1,3-dicarboxylates from acetone-1,3- dicarboxylates in high yields was developed by the use of DMC as a dehydrating reagent. This process opened a new expeditious mute to a 1- azabicyclo[3.3.0]octane skeleton of pyrrolizidine alkaloids from dimethyl acetone-1,3-dicarboxylate and bis(2-chloroethyl)amine via a Michael addition and a novel tandem cyclization.
