  A practical improvement of crystallization-induced asymmetric transformation of allene-1,3-dicarboxylates

  摘要：

  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 (+)-menthols, borneol, and isoborneol. After scrutinizing the crystallization of several allene-1,3-dicarboxylates in the presence of triethylamine, it was found that allene-1,3-dicarboxylate carrying bornyl groups was the most easily prepared as a single isomer because of it having suitable solubility to be crystallized in hexane at 0 degrees C to room temperature. Diels-Alder reaction of the enantiomerically pure allene-1,3-dicarboxylates and cyclic dienes, such as N-Boc-pyrrole and cyclopentadiene, afforded endo-adducts having the same configurations at two newly generated stereogenic centers.

  dialkyl succinates in high chemical yields by combination of alpha-carbonyl radical pairs produced by photochemical decarbonylation. It is proposed that the solid-state reaction depends on the exothermicity of two consecutive bond cleavage processes. It is also suggested that the efficiency of radical formation in the solid state is determined by the effect of substituents on bond dissociation energies
