  Total Synthesis of Everninomicin 13,384-1—Part 3: Synthesis of the DE Fragment and Completion of the Total Synthesis

  摘要：

  The stereoselective construction of the DE fragment (2) of everninomicin 13,384-1 (1) is reported. From the two possible ways of inserting the DE fragment between the A1B(A)C and FGHA2 domains of the natural product, the sequence involving the DEFGHA2 segment was found to be the most viable. This coupling was followed by attachment of a suitably protected and activated A1B(A)C fragment which led, after orthoester construction and final deprotection to the targeted everninomicin 13,384-1 (1), completing the total synthesis of this complex naturally occurring substance.

  1, whereas a heptanoyl homolog (2w: C7) maintained activity nearly equal to that of 1. When the acyl groups at these three positions were substituted by an octanoyl group (2i: C8), the activity was completely lost. On the other hand, of the 10 homologs in which the octanoyl at C-2 was substituted by other acyloxy moieties (2j–2s), three (2m: C7, 2n: C9, 2o: C10) maintained potent activity. These results
