Metal-free visible light-promoted synthesis of isothiazoles: a catalytic approach for N–S bond formation from iminyl radicals under batch and flow conditions
applying photoredoxcatalysis. This simple strategy features mild conditions, broad scope and wide functional group tolerance representing a new enviromentally friendly option to prepare these highly valuable heterocycles. Furthermore, the synthetic value of the method is highlighted by the preparation of a natural product derivative and the implementation of the reaction in a continuousflow setup.
Compounds of formula I:
are antagonists of the human 5-HT2A receptor, and hence useful in treatment or prevention of a variety of neurological conditions.
化学式为I的化合物是人类5-HT2A受体的拮抗剂,因此在治疗或预防各种神经系统疾病方面非常有用。
