The aldol addition of unphosphorylated dihydroxyacetone (DHA) to aldehydes catalyzed by L‐rhamnulose‐1‐phosphatealdolase (RhuA), a dihydroxyacetonephosphate‐dependent aldolase, is reported. Moreover, a single point mutation in the phosphate binding site of the RhuA wild type, that is, substitution of aspartate for asparagine at position N29, increased by 3‐fold the of aldol addition reactions of
Storable protection-free symmetrically branched oligoglycerols (BGL) reagents possessing alkoxyamine or thioisocyanate at apex, were developed. Oligohydroxylation with these new BGL reagents (BGLation) can be carried out under mild conditions.
