3-Aryl- and 3-alkyl-1H-2-benzothiopyran-1-ones are readily accessible by reaction of the lithiated N,N-diethyl-o-toluamide (N,N-diethyl-2-methylbenzenecarboxamide) with appropriate aromatic, heteroaromatic and aliphatic thioesters.
3-芳基和3-烷基-1H-2-苯并噻吩-1-酮可以通过锂化的N,N-二乙基邻甲苯酰胺(N,N-二乙基-2-甲基苯甲酰胺)与合适的芳香、杂芳香和脂肪族硫酯反应制备。
