Name is 5-Chlorobenzo[d]oxazole-2(3H)-thione, as a common heterocyclic compound, it belongs to benzoxazole compound, and cas is 22876-19-3, its synthesis route is as follows.,22876-19-3
(1) Synthesis of 4beta-S-(6-chlorobenzoxazole-2)-podophyllotoxin: 414 mg (1 mmol) of podophyllotoxin,201 mg (1 mmol) of 6-chlorobenzoxazole-2-thiol, dried under vacuum for 1 h, using 15 mL of trifluoroacetic acid as solvent in ice bath.The mixture was stirred under vacuum for 1 to 3 hours, and chloroform acetone was used as a developing solvent to detect the end point of the reaction. Adding the reaction system to 20 to 50 times the volumeIn deionized water, the filter cake was collected by filtration and washed to obtain a crude product.
With the complex challenges of chemical substances, we look forward to future research findings about 5-Chlorobenzo[d]oxazole-2(3H)-thione
