An efficient TMSOTf-promoted selective triple consecutive insertions of tert-butyl isocyanide into aldehydes has been developed, affording pharmacological interesting 4-cyanooxazoles in high yields in a one pot manner. The given method encompasses a wide range of substrates with tert-butyl isocyanide serving as sources of critical “CN” and “C–N═C” moieties. The versatile transformations of the resulting
已经开发出一种有效的 TMSOTf 促进的选择性三次连续插入异氰化叔丁基到醛中,以一锅法以高产率提供药理学上有趣的 4-氰基恶唑。给定的方法涵盖了广泛的底物,其中叔丁基异氰化物作为关键“CN”和“C-N=C”部分的来源。证明了所得 4-氰基恶唑的多种转化。确定了可能机制的关键反应中间体。
