Synthesis of 2-deoxy-L- and -D-galacto-heptose via inverse type hetero-Diels-Alder reaction

Inverse type hetero-Diels- Alder reaction based diastereoselective synthesis of higher sugars is performed with chiral carbon substituents in the 2-position of the 1-oxa-13-diene required as heterodiene. This is demonstrated for the synthesis of partially
