The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a downstream synthesis route of the compound 92-30-8,92-30-8
General procedure: To a solution of hydroxy compounds, sulfhydryl compounds oramino compounds (1.0 eq) and propargyl bromide (1.2 eq) inacetone (20 ml) was added NaOH (1.5 eq), the mixturewas refluxedfor about 6 h. Upon completion, the residue was purified withcolumn chromatography (hexane:EtOAc 7:1) to obtain analogue13a~13m. Sulfonyl chlorides (1.0 eq) and propynylamine (1.2 eq) inCH2Cl2 (20 ml) was added Et3N (1.5 eq), the mixture was stirred atroom temperature for about 6 h. Upon completion, the residue waspurified with column chromatography (hexane:EtOAc 9:1) toobtain analogue 13n~13o.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 92-30-8.
