Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...
