A novel phosphine-catalyzed [4 + 1] cyclization reaction was developed to construct the 3-oxo-3H-spiro[benzofuran-2,1'-cyclopentane] scaffold. Utilizing this innovative method, twenty diverse 3-oxo-3H-spiro[benzofuran-2,1'-cyclopentane] carboxylic acid derivatives were synthesized and evaluated for their anti-fibrotic activities. Compound L10-P1 possessed potential anti-fibrotic activity by inhibiting the expression of fibronectin, collagen I, and α-SMA. This study presents a new synthetic route for 3H-spiro[benzofuran-2,1'-cyclopentan]-3-one derivatives, contributing valuable insights into the chemical and biological diversity of these compounds.
开发了一种新型的膦催化[4 + 1]环化反应，用于构建3-氧代-3H-螺[苯并呋喃-2,1'-环戊烷]骨架。利用这种创新方法，合成了20种不同的3-氧代-3H-螺[苯并呋喃-2,1'-环戊烷]羧酸衍生物，并对其抗纤维化活性进行了评估。化合物L10-P1通过抑制纤连蛋白、I型胶原蛋白和α-SMA的表达而具有潜在的抗纤维化活性。本研究为3H-螺[苯并呋喃-2,1'-环戊烷]-3-酮衍生物提供了一条新的合成路线，为这些化合物的化学和生物多样性提供了有价值的见解。
