Because of their increased activity against activating mutants, first-generation epidermalgrowthfactorreceptor (EGFR) kinase inhibitors have had remarkable success in treating non-small-cell lung cancer (NSCLC) patients, but acquired resistance, through a secondary mutation of the gatekeeper residue, means that clinical responses only last for 8–14 months. Addressing this unmet medical need requires

We discovered a general and comprehensive approach for the regioselective hydroboration of terminal and internalalkynes to synthesize vinylboronates using inexpensive and magnetically separable copper ferrite nanoparticles at low catalyst loading using Bis(pinacolato)diboron in the absence of ligand and additives, under mild and greener conditions. A diverse range of functional groups was tolerated

using ruthenium-catalyzed olefin cross-metathesis of 1-propenyl pinacol boronate and various alkenes, including functionalized and 1,1-disubstituted alkenes. The resultant boronate cross products are stereoselectively transformed into predominantly Z-vinyl bromides and E-vinyl iodides. The vinyl bromides may be synthesized in a two-step, one-pot synthesis from a variety of olefins, resulting in a Z-selective

Transition-metal and ligand-free method for the hydroboration of terminalalkynes with B2pin2 was reported in LiOt-Bu/toluene/MeOH system under room temperature. Alkylalkynes and arylalkynes reacted efficiently with high regioselectivity.
