Abstract

A convenient and practical strategy for the construction of a natural amino sugar analogue, furanodictine B, isolated from the multicellular fruit body has been developed in an optically active form. The synthetic process is based on readily accessible and stereodefined manipulation of the highly functionalized bicyclic ­derivative incorporating the glucuronolactone-derived skeleton.

Direct deoxgenation with Et3SiH-Lews acid system after reduction of the lactone 4 to the corresponding lactol derivative, however, resulted in the preparation of the complex mixture.

Synthesized furanodictine B in this report was a mixture [α:β = 1:2.4 (natural; α:β = 2:3)1] of the two anomers.
