| Abstract: | Abstract The dimerization by hetero Diels-Alder reaction of methyl 4,6-O-benzylidene-3-deoxy-3-C-methylene-α-D-erythro-hexopyranosid-2-ulose was found to be regio and stereospecific. The structure of the cycloadduct was assigned from NMR spectrographic and X-ray crystallographic results. These results indicated that this cycloaddition occurred by a concerted hetero Diels-Alder reaction with inverse electron demand. |
