Using o-isothiocyanato-(E)-cinnamaldehydes as powerful and versatile precursors, a facile domino reaction for the simultaneous formation of a compound library similar to natural products 3,4-dihydroquinazoline derivatives and 2,4-dihydro-1H-benzo[d][1,3]thiazine derivatives has been developed. The domino reaction of o-isothiocyanato-(E)-cinnamaldehydes with hydroxylamine resulted in the simultaneous
使用邻异硫氰酸根-( E )-肉桂醛作为强大且多功能的前体,通过简单的多米诺骨牌反应,同时形成类似于天然产物3,4-二氢喹唑啉衍生物和2,4-二氢-1H-苯并的化合物库。d ][1,3]噻嗪衍生物已被开发。邻-异硫氰酸-(E )-肉桂醛与羟胺的多米诺反应导致同时形成N/S-杂环和N/N-杂环,生成六类以前未知的2,4-二氢-1H-苯并[ d][1,3]噻嗪衍生物具有各种官能团。该策略是面向多样性的合成方法的典型例子。
