标题 :Bio-intermediates for use in the chemical synthesis of polyketides
发明人：SANTI DANIEL; ASHLEY GARY; MYLES DAVID C
摘要:The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKSâ€?) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediatesâ€?) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greaty simplified.

权利人:DUBOIS JEAN-LUC; IBORRA CHORNET SARA; VELTY ALEXANDRA I LUCIENNE; CORMA CANOS AVELINO
摘要:A method for the synthesis of cyclic acetals comprises reacting at least one carbonyl-function compound selected from aldehydes, ketones, and/or linear acetals, on a polyol in a concentrated aqueous solution exceeding 20 wt % in a reactor containing an acidic catalyst. The carbonyl-function compound is selected so that the cyclic acetal obtained has a water solubility lower than 20000 mg/kg. During the catalytic reaction for the cyclic acetal synthesis, at least one portion of the organic phase containing the cyclic acetal is separated. The acidic catalysis is either homogeneous when using a water-soluble strong acid, or heterogeneous when using a solid acid such as a resin, a zeolite, or any appropriately acidified solid. The extractive reaction method can be used for obtaining high conversions and selectivity.
