摘要: Abstract A new approach to the synthesis of ulosonic acids KDO and DAH is described. The key step C 5 –C 6 bond formation catalysed by fructose-1,6-bisphosphate aldolase (for KDO) or transketolase DAH) using substituted acrylonitrile α-hydroxyaldehyde. All asymmetric carbon configurations are determined in an enzymatic means deshydrogenase lipase. This strategy, a non-metabolism pathway, allows access novel precursors KDO, analogues.
