in DMF to 2-(carbethoxymethyl)-8-methoxy-1-oxo-2,3-dihydro-1H-cyclopenta[a]naphthalene (8). Treatment of 8 with methanolic ammonia yielded the corresponding amide (9). Dealkylation of 8 with 48% HBr and subsequent esterification gave compound 10. Ammonolysis of 10 led to the amide 11, which after reduction and subsequent dehydration of the reduced product afforded the desired compound, 2-(carbamylm
通过在乙酸钠存在下用草酸二乙酯处理,将8-甲氧基-1-氧代-2,3-二氢-1H-环戊[a]萘(4)转化为草酰衍生物(7)。将钠盐形式的化合物7用溴乙酸乙酯在DMF中烷基化为2-(碳乙氧基甲基)-8-甲氧基-1-氧代-2,3-二氢-1H-环戊[a]萘(8)。用甲醇氨处理8,得到相应的酰胺(9)。8用48%HBr脱烷基并随后酯化,得到化合物10。10的氨解反应生成酰胺11,在还原并随后将还原的产物脱水后,得到所需的化合物2-(氨基甲酰基甲基)-8-羟基-3H-环戊[a]萘(2)。发现化合物2对培养物中的L1210和CCRF-CEM白血病细胞具有轻度生长抑制作用。根据热转变温度研究,
