Abstract
AbstractThis review aims to provide a comprehensive overview of condensation-based methods for the C–H bond functionalization of amines that feature azomethine ylides as key intermediates. These transformations are typically redox-neutral and share common attributes with classic name reactions such as the Strecker, Mannich, Friedel–Crafts, Pictet–Spengler, and Kabachnik–Fields reactions, while incorporating a redox-isomerization step. This approach provides an ideal platform to rapidly transform simple starting materials into complex amines.1 Introduction1.1 General Remarks1.2 Overview1.3 Scope of This Review2 Aromatization of Cyclic Amines2.1 Pyridines from Piperidine2.2 Isoquinolines from Tetrahydroisoquinolines and Quinolines from Tetrahydroquinolines2.3 Pyrroles from 3-Pyrroline or Pyrrolidine2.4 Indoles from Indolines3 Pericyclic Reactions3.1 (3+2)-Dipolar Cycloadditions3.2 6π-Electrocyclizations3.3 1,5-Proton Shifts4 Redox-Variants of Classic Transformations Incorporating a C–H Bond Functionalization Step4.1 α-Cyanation4.2 α-Alkynylation4.3 α-Phosphonation4.4 α-Arylation4.5 α-Alkylation with Ketones4.6 Redox-Ugi Reaction4.7 Miscellaneous Intermolecular Reactions5 Redox-Annulations6 Reactions Involving β-C–H Bond Functionalization7 Outlook

Abstract
An efficient discovery strategy by combining diversity-oriented synthesis and converging cellular screening is described. By a three-round screening process, we identified novel tricyclic pyrido[2,3-b][1,4]benzothiazepines showing potent inhibitory activity against paclitaxel-resistant cell line H460TaxR (EC50 < 1.0 μM), which exhibits much less toxicity toward normal cells (EC50 > 100 μM against normal human fibroblasts). The most active hits also exhibited drug-like properties suitable for further preclinical research. This redeployment of antidepressing compounds for anticancer applications provides promising future prospects for treating drug-resistant tumors with fewer side effects.
