  Studies on the Synthesis of Quartromicins A₃ and D₃:  Synthesis of the Vertical and Horizontal Bis-Spirotetronate Fragments

  摘要：

  Syntheses of the vertical (3) and horizontal (4) bis-spirotetronate units of quartromicins A(3) and D-3 are described, along with an efficient synthesis of alpha-hydroxy aldehyde exo-8b, a precursor to the exo-spirotetronate fragments 19 and 21.

  Diastereoselective Synthesis of the endo- and exo-Spirotetronate Subunits of the Quartromicins. The First Enantioselective Diels−Alder Reaction of an Acyclic (Z)-1,3-Diene

  摘要：

  Diastereoselective syntheses of the endo- and exo-spirotetronates 1 and 2, corresponding to the galacto and agalacto fragments of quartromicins A(3) and D-3, are described. The key step of these syntheses are highly enantio- and diastereoselective Lewis acid catalyzed Diels-Alder reactions of the 1,1,3,4-tetrasubstituted diene 3.
