  Synthesis of Vinca Alkaloids and Related Compounds. 90.¹ New Results in the Synthesis of Alkaloids with the Aspidospermane Skeleton. First Total Synthesis of (±)-3-Oxominovincine

  摘要：

  The tryptamine derivative 1 readily reacted with methyl 4-acetyl-5-bromopent-4-enoate (9) that had been built up from 2,4-pentanedione. On intramolecular dehydration and subsequent [4 + 2] cycloaddition, the reaction product 10 gave the epimers 12 and 13 having the D-secoaspidospermane skeleton. Compound 12 directly and 13 after epimerization yielded (+/-)-3-oxominovincine (14). Regioselective reduction of 14 furnished (+)-minovincine (17).

  A molecule with an indole skeleton, containing a latent acrylic ester function—acting as a diene—was produced from Nb-trityl-2-(hydroxy-methyl)-tryptamine and reacted with esters containing an aldehyde or aldehyde-equivalent structural unit, yielding 3-oxo-16,17-dihydro-Δ20-secodin-17-ol type intermediates from which dehydration, followed by [4+2]cycloaddition, furnished 3-oxovincadifformine and 3-oxominovincine

  由N b-三苯甲基-2-（羟基-甲基）-色胺产生具有吲哚骨架的分子，该分子具有潜在的丙烯酸酯功能（起二烯作用），并与含有醛或醛当量结构单元的酯反应，得到3-氧代-16,17-二氢- Δ 20 -secodin -17-醇型中间体从脱水，接着[4 + 2]环加成，陈设3- oxovincadifformine和3- oxominovincine。我们还希望将该方法用于生产15β-羟基长春新碱，但是，观察到具有吲哚骨架的二聚产物的出现，而不是预期的环加成。
