Tandem: Allylic alcohols react with N‐chlorosuccinimide (NCS) in a tandem 1,3‐H shift/CCl bond formation leading to α‐chloroketones and α‐chloroaldehydes. The reactions proceed with complete selectivity to give single constitutional isomers of monochlorinated carbonyl compounds. The utility of the transformation is illustrated by the straightforward synthesis of 4,5‐disubstituted 2‐aminothiazoles
串联:烯丙醇与N-氯代琥珀酰亚胺 (NCS) 串联 1,3-H 位移/C - Cl 键形成反应,生成 α-氯酮和 α-氯醛。反应完全选择性地进行,得到单氯化羰基化合物的单一结构异构体。从烯丙醇直接合成 4,5-二取代 2-氨基噻唑说明了该转化的实用性。
