Abstract:

The purpose of this paper is to achieve the high value-added and diversified transformation of the renewable biomass (-)-shikimic acid, starting from which, the key intermediate (-)-methyl-3-dehydroshikimiate was readily obtained through esterification and 2-iodoxybenzoic acid-oxidation. The reaction of (-)-methyl-3-dehydroshikimiate with hydrazine, acethydrazide, hydrazinobenzene and acetamide could give rise to non-aromatization products(2a and 2d), partial-aromatization products(2b) and aromatization products(2c and 2e) selectively under different conditions. The present methodology with good diversity, high selectivity and operational simplicity provides a new paradigm for the transformation of bio-based and non-food feedstock.

Key words: (-)-Methyl-3-dehydroshikimate, Hydrazine compound, Selectivity, Renewable source
