  Synthesis of glycolipid analogs via highly regioselective macrolactonization catalyzed by lipase

  摘要：

  Highly regioselective lipase catalyzed macrolactonization has been used in synthesizing first feedstock based glycolipid analogs. These macrolides containing common disaccharides maltose (4-O-alpha-D-glucopyranosyl-beta-D-glucose) and melibiose (6-O-alpha-D-galactopyranosyl-beta-D-glucose) were synthesized by employing chemoenzymatic methodologies. Maltose and Melibiose were coupled with methyl 15-hydroxy pentadecanoate and then subjected to a highly regioselective macrolactonization at the C-6" position using Candida antarctica lipase-B to yield the desired products.
