development of the synthesis for an unusual and rare class of compounds – 8‐ylidenebenzazecines. The target compounds were synthesized via two strategies and obtained in high and good yields. The first method is an efficient MW‐assisted rearrangement of azacyclic allenes, the second one represents one‐pot protocol based on enlargement of tetrahydropyridine moiety to 8‐ylidene decorated azecine ring.

New approach for the introduction of a perfluoroalkynyl fragment into 1-R2–2-methyl-1,2,3,4-tetrahydroisoquinolines has been developed. Synthesized 1,1-disubstituted isoquinolinecompounds under the action of methyl propiolate (24 °C) and acetylacetylene (-17 °C) in trifluoroethanol are converted into 6-perfluoroalkyl substituted allene benzazecines. The synthesized isoquinolinederivatives 2, and
开发了将全氟炔基片段引入 1-R 2 –2-甲基-1,2,3,4-四氢异喹啉的新方法。合成的1,1-二取代异喹啉化合物在三氟乙醇中丙炔酸甲酯(24℃)和乙酰乙炔(-17℃)的作用下转化为6-全氟烷基取代的丙二烯苯并西辛。合成的异喹啉衍生物2和苯扎西因3 – 4针对四种癌细胞系进行了评估。结果表明化合物2h (R 2 = C 6 H 4 - p -OMe; R F = CF(CF 3 ) 2) 对四种测试细胞系显示出良好的细胞毒性作用,IC 50值范围为 5 至 50 μM。
