The hydrolytic imidazoline ring expansion (HIRE) methodol. was extended to readily available tetracyclic [1,4]thiazepines as well as sulfoxide and sulfone analogs thereof. The reactions resulted in the facile formation of a rare medium-sized [1,4,7]thiazecine ring system that has an emerging utility in bioactive compound design. Comparing the HIRE rates for representative compounds in the three groups of substrates allowed drawing some generalizations about the substituent effects on the course of the reaction. In the experiment, the researchers used many compounds, for example, Methyl 6-chloro-5-nitronicotinate (cas: 59237-53-5Quality Control of Methyl 6-chloro-5-nitronicotinate).
Methyl 6-chloro-5-nitronicotinate (cas: 59237-53-5) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Quality Control of Methyl 6-chloro-5-nitronicotinate
