  Synthesis of a tetramethyl analog of teleocidin

  摘要：

  A simplified tetramethyl analogue 3 of Teleocidin B-4 (1) has been synthesized from dinitrotoluene 6 via indole 4. The valine moiety of analogue 3 was provided by the coupling of (N-methylamino)indole 16 derived from 4 with the triflate of (R)-2-hydroxyvaleric acid benzyl ester, and the tryptophanyl portion was constructed by alkylation of the resulting (S)-N-valylindole 17 with ethyl (3-bromo-2-oximido)propionate to give the oxime 18. After reduction to the diastereomeric amines 20 and 21, closure to the 9-membered lactam-esters 24 and 23 (respectively) was accomplished using BOP. Separation and reduction of the esters led to teleocidin analogue 3 and its epimeric alcohol 25, respectively.
