Allylation and propargylation of oxidized raffinose
All reactions were done in plain water. The reactions between
enzymatically oxidized raffinose (Raf-CHO) and allyl bromide or
cinnamyl chloride proceeded at room temperature. According to
MALDI–MS analysis of the reaction solution, the reaction with
allyl bromide was complete after 24 h, and since only the expected
product peaks of allylated raffinose (m/z = 567, Na+ adduct;
m/z = 583, K+ adduct) were detected (Fig. 2 and Table S1 in supplementary
data), the reaction was assumed to have a yield of
100%. This was well in accordance with the results obtained
