Chemoenzymatic formal synthesis of (S)-(−)-phosphonotrixin
摘要:
Phosphonotrixin is a herbicidal antibiotic characterized by a unique structure bearing a C-P bond on an isoprene unit. The formal enantioselective synthesis of (S)-(-)-phosphonotrixin (ee = 93%) in nine steps and 12% overall yield from 1,3-dihydroxyacetone or in eight steps and 11% overall yield from 1,3-dichloroacetone is reported. The key reaction is the enzymatic desymmetrization of 2-isopropenylpropane-1,2,3-triol. (C) 2004 Elsevier Ltd. All rights reserved.
