  Non-canonical regioisomerizations and a ‘Diels–Alderase’ are likely essential in the biosynthesis of Spiculoic acid A

  摘要：

  The regiochemistry of dehydration and cyclization steps of the linear biosynthetic precursor of the polyketide natural product Spiculoic acid A (1) were examined. Herein we describe the synthesis of polyene-containing aldehyde 21, a counterpart to the metabolite's putative polyketide intermediate and demonstrate its inability to undergo facile IMDA chemistry. These results suggest the involvement of a non-canonical regioisomerization in the biosynthesis of 1, and that the IMDA reaction is likely enzyme-catalyzed. (c) 2012 Elsevier Ltd.
