- Preparation process of sertaconazole nitrate
-
The invention provides a preparation process of sertaconazole nitrate. The preparation process comprises the following steps: acylating, cyclizing, brominating, salifying and refining to obtain the finished product of sertaconazole nitrate. By adopting the preparation process of sertaconazole nitrate, the obtained finished product of sertaconazole nitrate is high in purity and high in yield. By adopting the preparation process of the sertaconazole nitrate, the raw materials are fully reacted, the generation of impurities is effectively reduced, the purity of a crude product is greatly improved, finally, the finished product of the sertaconazole nitrate obtained by adopting a refining process is high in purity and yield, and the production benefit of a sertaconazole nitrate bulk drug is effectively improved.

- Synthesis of α-arylthioacetones using TEMPO as the: C 3 synthon via a reaction cascade of sequential oxidation, skeletal rearrangement and C-S bond formation
-
Here, we present an unprecedented pathway to α-sulfenylated carbonyl compounds from commercially available thiols and universally employed TEMPO and its analogues, which act as C3 synthons through skeletal rearrangement under simple and metal-f

- α-Arylchalcogenation of acetone with diaryl dichalcogenide via metal-free oxidative C(sp3)-H bond functionalization
-
Direct α-arylchalcogenation of acetone with diaryl dichalcogenides has been achieved by using a mixture of TBHP and DTBP oxidants at 120 °C without transition-metal catalyst via oxidative C(sp3)-H bond functionalization. The method exhibits good functional group tolerance and products were isolated in moderate to high yields.
