of the corresponding diacetyl-substituted precursor was interpreted by the electron-releasing effect of the ferrocenyl- or phenothiazinyl group present in the β position of the enone subunit. The structures of the novel products were evidenced by IR, 1 H and 13 C NMR spectroscopy including 2D-COSY, 2D-HSQC and 2D-HMBC measurements.
摘要 通过1-酰基-/1,1'-二酰基二茂铁(酰基甲酰基或乙酰基)与3-甲酰基-和3,7-二乙酰吩噻嗪的碱催化缩合反应,制备了一系列新型单-和双-查耳酮。单查耳酮中间体的烯醇化物阴离子相对于相应的双乙酰取代前体的烯醇化物的反应性增强,可以通过存在于烯酮亚基 β 位置的二茂铁基或吩噻嗪基的电子释放效应来解释. 新产品的结构由 IR、1 H 和 13 C NMR 光谱证实,包括 2D-COSY、2D-HSQC 和 2D-HMBC 测量。
