Easily available and nontoxic FeCl3 catalyzes intramolecular oxidative coupling for the direct construction of the phenanthrene ring using meta-chloroperbenzoic acid as sole oxidant at room temperature in excellent yields. The mechanistic investigations show that FeCl3-catalyzed coupling proceeds through the heterolytic coupling (A+ + B). The catalytic approach has been applied to intermolecular biaryl
A nontoxic FeCl3 catalyzed intramolecular oxidative coupling reaction was developed for mild synthesis of a series of phenanthrenes with different substituents. The method involves cross dehydrogenative coupling of a variety of 1,2‐diarylethylene derivatives with di‐tert‐butylperoxide (DTBP) as a sole oxidant at room temperature in CH2Cl2/TFA (9:1 V/V) to yield phenanthrenes in good to excellent yields

research in our lab found that natural phenanthrenes derived from Traditional Chinese Medicine Baiyangjie could inhibit liver fibrosis through inhibiting TGF-β1, TNF-α and promoting the secretion of MMP-9. Herein, in order to optimize the structure of phenanthrenes to maximize their anti-fibrosis activities, a series of phenanthrene derivatives were designed and synthesized in an expeditious manner. Their
