6-Tuliposides A (PosA) and B (PosB) are glucose esters accumulated in tulip (Tulipa gesneriana) as major defensive secondary metabolites. Pos-converting enzymes (TgTCEs), which we discovered previously from tulip, catalyze the conversion reactions of PosA

Regioselective differentiation of the hydroxy groups of mono- and oligosaccharide substrates is necessary to form building blocks that can be used for synthetic transformations. In this paper, we show that iron(III) chloride hexahydrate catalyses the tandem protection of mono- and disaccharides to give, in a one-pot procedure, selectively protected carbohydrate building blocks. This tandem protocol was successfully applied to a trisaccharide. The procedure is easy to carry out; for optimal results, each carbohydrate substrate required a fine tuning of the one-pot reaction conditions.

Toward the total synthesis of 6-tuliposide B, facile synthesis of tulipalin B and 1-O-methyl-6-tuliposide B (Methyl 6-0-((S)-3′,4′-dihydroxy-2′-methylenebutanoyl)-β-D-glucopyranoside) has been achieved.
