the stereoselectivesynthesis of various (E)-, (Z)-, and disubstituted 3-alkylideneoxindoles via radical cyclization reactions were investigated using tandem indium-mediated carbometallation and palladium-catalyzed cross-couplingreactions. The proper combination of substrates and reaction conditions is important for good yields. The key step is the first stereoselective carboindation reaction using

Cyclization Cascade, Sequential Amination/Etherification for Stereoselective Construction of 3‐Methyleneindolinones
An cascade intramolecular 5‐exo‐dig cyclization of N‐(2‐iodophenyl)propiolamides and sequential amination/etherification (with N‐hydroxybenzamides, phenyl hydroxycarbamate) protocol for the synthesis of amino‐ and phenoxy‐substituted 3‐methyleneindolinones using unexpensive Pd(PPh3)4 as catalyst has been developed. The protocol enables the assembly of structurally important oxindole cores featuring

A series of combretastatinA4 (CA4) analogues with a lactam or lactone ring fused to the trimethoxyphenyl or the B‐phenyl moiety were synthesized in an efficient and stereoselective manner by using a domino Heck–Suzuki–Miyaura coupling reaction. The vascular‐disrupting potential of these conformationally restricted CA4 analogues was assessed by various in vitro assays: inhibition of tubulin polymerization
