ABSTRACT:
A ruthenium catalyzed method to synthesize cyclic sulfate compounds from the corresponding cyclic sulfites, and the cyclic sulfate reaction products obtained by this method. These cyclic sulfates further react with selected nucleophiles to give various substituted products. The method is an efficient means for the synthesis of chiral building blocks from tartaric acid enantiomers in high yields using an overall two-stage, one-pot reaction procedure. The chiral compounds can be transformed by nucleophilic reactions into chiral building blocks useful for the synthesis of natural biologically active products, such as antibiotics and pheromones.
