Herein, Cu–HMT and Ni–HMT were synthesized via a green synthetic method. Cu–HMT possesses formidable peroxidase-mimic activity compared to Ni–HMT. However, the peroxidase-like activity of Cu–HMT was strongly inhibited in the presence of DA.

One Step

<div>We report here a catalytic, Markovnikov selective, and scalable synthetic method for the synthesis of saturated sulfur heterocycles, which are found in the structures of pharmaceuticals and natural products, in one step from an alkenyl thioester. Unlike a potentially labile alkenyl thiol, an alkenyl thioester is stable and easy to prepare. The powerful Co catalysis via a cobalt hydride hydrogen atom transfer and radical-polar crossover mechanism enabled simultaneous cyclization and deprotection. The substrate scope was expanded by the extensive optimization of the reaction conditions and tuning of the thioester unit.</div>
