Article Abstract
Herein, we report a concise synthetic approach to gliflozin (SGLT2 inhibitors) aglycones from generating regioselective ortho-lithiation based on differentiating the acidifying effect of 1,4-dihalobenzenes and reacting with (hetero)aromatic aldehydes. Then, the resulting diarylmethyl alcohol was converted to diarylmethane using acid-mediated reduction, offering a two-step practical method for synthesizing aglycones of various gliflozins such as Dapagliflozin, Empagliflozin, and Ipragliflozins.

Iron-Catalyzed Asymmetric [4+2]/Cheletropic Retro-[4+1] Cycloadditions of Thiophene S,S-Dioxides with 3-Substituted Indoles.

The Diels-Alder/cheletropic retro-[4+1] cycloadditions of thiophene S,S-dioxides are a prominent method for synthesizing unsaturated six-membered carbocycles. However, to the best of our knowledge, catalytic asymmetric variations of these reactions have not yet been achieved. Herein, we report Fe(III)-bis(oxazoline) complex-catalyzed inverse-electron-demand [4+2] cycloaddition/cheletropic retro-[4+1] extrusion of SO reactions between thiophene S,S-dioxides and 3-substituted indoles.

A concise enantioselective total synthesis of leptosphine C () has been achieved. Our synthetic strategy features an unprecedented diastereo-/enantioselective Hajos-Parrish-Eder-Sauer-Wiechert (HPESW) reaction for construction of the AB ring system with continuous stereogenic centers (76% yield, 90% ee, dr = 19:1) and an uncommon Pauson-Khand (PK) reaction of geminal dimethyl alkenyl side chains for establishing the CD ring system with the quaternary carbon at C14.

The Hedgehog signaling pathway plays an essential role in cancer progression, including in basal cell carcinoma and medulloblastoma. This process is driven by oncogenic Gli transcription factors, which are regulated by the signaling protein Smoothened (Smo). While Smo inhibitors have shown clinical utility, drug resistance can limit their effectiveness.

Herein, the first Lewis acid-catalyzed ring-opening reaction of bicyclobutanes (BCBs) with acyclic thioamides for the concise, modular synthesis of 1,1,3-trisubstituted cyclobutanes is described. These products feature valuable iminothioether-substituted cyclopropane moieties and single-configuration tetrasubstituted carbon stereocenters. The reaction proceeds under mild conditions and accommodates diverse acyclic thioamides and substituted acyl-BCBs, exhibiting excellent nucleophilic selectivity (S-H/N-H > 99/1) and chemoselectivity (/ > 98/2).
