The asymmetric and divergent total syntheses of two phragmalin (moluccensins G H) khayanolide-type (krishnolide F khayseneganin F) limonoids were disclosed, which employed a torquoselective interrupted Nazarov cyclization as the key step. Taken together with Liebeskind-Srogl coupling, benzoin condensation, bidirectional acyloin rearrangements, our strategy would simplify synthetic design both facilitate their modular syntheses. Moreover, described approach also provides additional insights into biosynthetic relationships between these distinct skeletons.

Abstract Benzothiophenes, activated by oxidation to the corresponding S ‐oxides, undergo C−H/C−H‐type coupling with phenols give C4 arylation products. While an electron‐withdrawing group at C3 of benzothiophene is important, process operates without a directing and metal catalyst, thus rendering it compatible sensitive functionalities—e.g. halides formyl groups. Quantum chemical calculations suggest formal stepwise mechanism involving heterolytic cleavage aryloxysulfur species π‐complex phenoxonium cation. Subsequent addition cation position favored over C3; Fukui functions predict that major regioisomer formed more electron‐rich between C4. Varied selective manipulation products showcase synthetic utility metal‐free process.
