  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.
