  “Tandem” reactivity of 2-Cyano-Δ3-piperideines II: Endocyclic versus exocyclic iminium ion reactions

  摘要：

  The C-7 substituted 2-cyano-DELTA-3-piperideine 2 reacts regioselectively with indole to give a 2/1 mixture of 4-(3-indolyl)piperidines 11 which were converted in four steps to the tetrahydropyridocarbazole derivative 16.

  Synthesis of 20-deethylsilicine from a second-generation 2-cyano-.DELTA.3-piperidine synthon

  摘要：

  The Zn2+ ion mediated reaction of the 2-cyano-DELTA3-piperidine 9a (X = SO2C6H5) with the silyl enol ether of Na-methyl-2-acetylindole (24) led to formation of compounds 29a,b (70%) resulting from introduction of the acetylindole moiety at the exocyclic (C-7) carbon center and migration of the phenylsulfonyl group from C-7 to C-4. In contrast, reaction of 2-Cyano-DELTA3-piperidine 9b (X = CN) with 24 gave the desired C-4 acetylindole-substituted products 36a,b (1:1.3 mixture; 72% overall yield). Attempts to cyclize intermediates 36 to the tetracyclic enamine 27 were unsuccessful. Alternatively, the Zn2+-catalyzed reaction of synthons 9a and 9b with indole gave the C-7 indole-substituted aminonitriles 37a,b and 38, respectively. These intermediates were converted to DELTA2-piperidine 40 on reaction with sodium dimethyl malonate and AgBF4. Stereoselective hydrogenation of the enamine double bond in 40 furnished the required cis 3,4-disubstituted piperidine 41, which was cyclized under acidic conditions to the target molecule, 20-deethylsilicine (20).

  A new and versatile synthesis of tetracyclic compounds 10, 22 and 24 presenting the ABED ring system of Strychnos alkaloids is described by closure of the C1C11b bond in the key step. The intermediate tetrahydropyridinium salts 2 have been obtained from 2-(1,3-dithian-2-yl)indole (3) and either 2-cyano-3-ethyl-1-methyl-1,2,3,6-tetrahydropyridine (4a) or N-substituted Δ3-piperidein-2-ones (5).
