《Thiophene isosters of isoquinoline. VI. Synthesis of 4,5-dimethylthieno[2,3-c]pyridine and 6,7-dimethylthieno[3,2-c]pyridine》 was published in Chemica Scripta in 1975. These research results belong to Sandberg, Elina. SDS of cas: 13250-82-3 The article mentions the following:
4,7-Dimethylthieno[2,3-c]pyridine (I) was synthesized by hydrolyzing the acetal function in 2-amino-3-[2-(1,3-dioxolan-2-yl)-3-thienyl]butan-3-ol (II) leading to the ring-closed and dehydrated product. The amine was obtained by the reaction of 2-(3-lithio-2-thienyl)-1,3-dioxolane with diacetyl, followed by oximation and reduction 6,7-Dimethylthieno[3,2-c]pyridine (III) was obtained in an analogous manner. The experimental part of the paper was very detailed, including the reaction process of 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3SDS of cas: 13250-82-3)
2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3) is one of dioxolane. 1,3-Dioxolane derivatives are recognized as important motifs for the construction of numerous pharmacologically active molecules as antiviral, antifungal, anti-HIV, and adrenoreceptor antagonists.SDS of cas: 13250-82-3
