derivatives 3 was performed through a Mannich-type condensation between 2-cyano-5-hydroxy-3-methylnaphtho[1,2]furan 2a, 1.5 eq of a primary amine and 3 eq of formaldehyde. Similarly, 2-cyano-5-hydroxy-3-methylfuro[2,3-f]quinoline 2b gave the dihydro furo[1,3]oxazino-quinoline compounds 4. Heating a mixture of the naphthofuran 2a, tert-butylamine and formaldehyde at toluene reflux led to the furonaphthoxazine
二氢呋喃并[1,3]恶嗪衍生物3的合成是通过2-氰基-5-羟基-3-甲基萘[1,2]呋喃2a,1.5当量的伯胺和3当量的Mannich型缩合反应进行的甲醛。类似地,2-氰基-5-羟基-3-甲基呋喃[2,3-f]喹啉2b得到二氢呋喃[1,3]恶嗪-喹啉化合物4。加热萘并呋喃2a,叔丁胺和甲醛的混合物在甲苯回流下,产生呋喃萘并恶嗪3e,其分解得到邻醌甲基化物中间体5。后者用1-吗啉代丙烯捕获,得到二氢呋喃并吡喃衍生物6。所有化合物2、3、4和6均在体外进行了分析。对L 1210,MDA-MB 231和PC肿瘤细胞具有细胞毒活性。其中,呋喃并[1,3]恶嗪3b,3c和呋喃[1,3]恶嗪喹啉4c,
