anilines. The reaction of the indicated aminonitrile with 4-chlorobutanoyl chloride and subsequent cyclization of the intermediate amide gave rise to 2-(3-chloropropyl)-3H-spiro[benzo[h]quinazoline-5,1′-cycloheptane]-4(6H)-one, which in the presence of potassium hydroxide underwent cyclization to form 10,11-dihydro-5H-spiro[benzo[h]pyrrolo[2,1-b]quinazolin-6,1′-cycloheptane]-7(9H)-one. The reaction of the
摘要 通过4'-氨基-1'H-螺[环庚烷-1,2'-萘]-3'-甲腈与苯胺的缩合合成相应的席夫碱。指定的氨基腈与 4-氯丁酰氯的反应和随后的中间体酰胺的环化产生 2-(3-氯丙基)-3 H-螺[苯并[ h ]喹唑啉-5,1'-环庚烷]-4( 6 H )-one,在氢氧化钾存在下环化形成 10,11-dihydro-5 H -spiro [benzo[ h ]pyrrolo[ 2,1- b ]quinazolin-6,1'-cycloheptane]- 7(9小时)-一。氨基腈与 3-氯-3-氧代丙酸乙酯的反应和相应的中间体酰胺的环化得到 2-(4-氧代-4,6-二氢-3 H-螺[苯并[ h ]喹唑啉-5乙酯, 1'-环庚烷]-2-基)乙酸酯。后者水解得到2-甲基-3 H-螺[苯并[ h ]喹唑啉-5,1'-环庚烷]-4(6 H )-酮,进一步与芳香醛缩合得到具有抗肿瘤特性的杂芪类。
