  Synthesis, antimicrobial and cytotoxicity study of 1,3-disubstituted-1H-naphtho[1,2-e][1,3]oxazines

  摘要：

  A series of new 1,3-disubstituted-1H-naphtho[1,2-e][1,3]oxazines (3 and 7) was synthesized in good yields and the structure was determined with the help of NMR, 2D-NMR, HRMS studies and X-ray crystallography. These compounds were tested in vitro for their antibacterial activity against Gram-positive and Gram-negative bacteria and as well as for antifungal activity. The compounds 3c, 3e, 7a, 7d and 7k showed significant antibacterial activity and 71 showed moderate antifungal activity. The cytotoxicity of 1,3-disubstituted-1H-naphtho[1,2-e][1,3]oxazines showed that 3e and 7e are more effective against breast, lung and colon cell proliferation. (C) 2012 Elsevier Masson SAS.

  the reactions of o-quinone methide precursors with imino ethers. The reaction provides a versatile route to substituted 1,3-benzoxazines. The proposed reaction mechanism involves the generation of the o-quinone methide intermediates, imino-Diels–Alder reaction, and elimination. This cascade process is a rare example of the participation of imino ethers as dienophiles.

  我们已经研究了邻醌甲基化物前体与亚氨基醚的反应。该反应提供了取代的1，3-苯并恶嗪的通用途径。拟议的反应机制涉及邻醌甲基化物中间体的产生，亚氨基-狄尔斯-阿尔德反应和消除。这种级联过程是亚氨基醚作为亲双烯体参与的罕见例子。
