The optically active lipid A-subunit homologs named GLA-46, GLA-47, GLA-59, and GLA-60 have been synthesized stepwise by successive acylation at N-2 and O-3 of benzyl 2-amino-2-deoxy-4,6-O-isopropylidene-beta-D-glucopyranoside with the 3-9O-(benzyloxy)methyl or 39O-tetradecanoyl derivative of optically active 3-hydroxytetradecanoic acid, and phosphorylation at O-4 of the D-glucosamine residue.
光学活性脂质A亚基的同系物,称为GLA-46,GLA-47,GLA-59和GLA-60,是通过在苄基2-氨基-2-脱氧-的N-2和O-3处连续酰化而逐步合成的。具有光学活性3-羟基十四烷酸的3-9O-(苄氧基)甲基或39O-十四烷酰基衍生物的4,6-O-异亚丙基-β-D-吡喃葡萄糖苷,并在D-葡萄糖胺残基的O-4处磷酸化。
