The current study reports the synthesis of different derivatives of benzoselenophene analogs as well as a diverse series of compounds (14a–p, 15 and 16) from 1,2,9,9a-tetrahydrocyclopropa[c]benzo[e]indol-4-one (CBI) and benzoselenophene or heteroaromatic acids. The overall yield of scaffold 12 was improved by an one-pot reaction, which helps in large-scale synthesis of CBI, a duocarmycin alkylation
目前的研究报道了由1,2,9,9a-四氢环丙烷[ c ]苯并[ e ]吲哚-4-合成苯并硒吩类似物的不同衍生物以及一系列不同的化合物(14a–p,15和16)一(CBI)和苯并硒基苯或杂芳族酸。脚手架的总产量12一锅法改善了这种反应,这有助于大规模合成CBI,一种双卡霉素烷基化亚基类似物。评价了该系列化合物对SK-OV3卵巢癌细胞系的细胞毒性,这表明苯并硒吩烯可以在取代吲哚部分后增强或维持杜卡霉素类似物的抗癌活性。CBI-benzoselenophenes与Ñ酰氨基在C-5位,取代基14克,14F和16(IC 50 = 0.5,1.2和1.6纳米,分别地),被认为是比CBI-TMI和其它苯并硒吩类似物更有效。Cf-苯并硒吩类似物14f和14g(含N分别发现-乙酰氨基和N-丁酰胺基取代基的效力分别是相应的CBI吲哚类似物14q和14r的8倍和120倍。

The reduction of selenium with lithium in THF in the presence of diphenylacetylene as a catalyst afforded lithium diselenide, which reacted with electrophiles giving alkyl or aryl diselenides 1 - 3 and selenides 4, as by-products. The useful method for preparation of diselenides based on this reaction was elaborated.

possible to utilize both equivalents of the selenenylating agent. The procedures work well for the majority of nucleophiles in a pKa range between more acidic malononitrile or Meldrum acid and less acidic phenylacetates. The reaction carried out on diethylmalonate in boiling rectified ethanol yields selenoacetate, which cannot be obtained by direct phosphoroselenenylation. Crystal structure of one of the
Convenient Syntheses of N,N-Dialkylselenoamides and N,N,N′,N′-Tetraalkylselenoureas by Treating Terminal<i>gem</i>-Dihaloalkanes, Chloroform, or Sodium Trichloroacetate with a Base, Elemental Selenium, and Amines
Treatment of terminal gem-dihaloalkanes, chloroform, or sodium trichloroacetate with elemental selenium in the presence of NaH and an excess amount of primary or secondary amines gave selenoamides and selenoureas in modest yields.
