The structure of three pyrrolisidinediones was determined by x-ray crystallographic analysis.A pseudocentrosymmetrical structure of the dimer crystal with a molecule of water of crystallization close to the inversion center was detected in the oxidation product.

, p. 156 - 159 (2007/10/03)
The thermal transformations of phthalimido-substituted keto-stabilized sulfonium ylides, including optically active ylides, were studied. The thermolysis of sulfonium ylides obtained from α and β-amino acids leads to methylthio-substituted pyrrolizidine-
