The reaction of indole-containing hydroxamates with aldehydes in the presence of Lewis acid leads to oxo N-acyliminium ions, which cyclize to the corresponding N-O fused [1,2]oxazino[4,5- B]indole, [1,2]oxazepino[4,5- B]indole, and [1,2]oxazocino[4,5- B]indole derivatives in good yields.
在路易斯酸存在下,含吲哚的异羟肟酸盐与醛反应产生氧代 N-酰基亚胺离子,其环化为相应的 NO 稠合的 [1,2] 恶嗪 [4,5- B]吲哚,[1,2] oxazepino[4,5- B]indole 和 [1,2]oxazocino[4,5- B]indole 衍生物的收率很高。
