From five to two: The addition of deprotonated Strecker products to N‐acylimines permits the synthesis of tetrasubstituted imidazoles or trisubstituted oxazoles in three or four steps, respectively. In total, the target compounds are prepared from two aldehydes, a primary amine, an acid chloride and ammonia (see scheme).
从5到2:向N-嘧啶中添加去质子化的Strecker产品可以分别通过三步或四步合成四取代的咪唑或三取代的恶唑。总而言之,目标化合物是由两种醛(伯胺,酰氯和氨)制得的(请参见方案)。
