  Casuarine Stereoisomers from Achiral Substrates: Chemoenzymatic Synthesis and Inhibitory Properties

  摘要：

  A straightforward chemoenzymatic synthesis of four uncovered casuarine stereoisomers is described. The strategy consists of L-fuculose-l-phosphate aldolase F131A-variant-catalyzed aldol addition of dihydroxyacetone phosphate to aldehyde derivatives of 1,4-dideoxy-1,4-imino-o-arabinitol (DAB) and its enantiomer (LAB) and subsequent one-pot catalytic deprotection reductive amination. DAB and LAB were obtained from dihydroxyacetone and aminoethanol using D-fructose-6-phosphate aldolase and L-rhamnulose-l-phosphate aldolase catalysts, respectively. The new ent-3-epi-casuarine is a strong inhibitor of alpha-D-glucosidase from rice and of rat intestinal sucrase.
