tandem acylation reactions of 2-quinolylzincates under one-potreaction conditions facilitated the formation of biologically active (Z)-3-alkylidenephthalides and multifunctionalized quinoline derivatives at specific positions. The reactions of these zincates with allyl iodide produced three different types of temperature- and alkyl-ligand-dependent C-2 homologated quinolines. The reaction mechanisms for

A highly efficient synthesis of trans-alkenylazaarene under catalyst-free conditions was developed via the addition of methylazaarenes to N-sulfonyl aldimines and a subsequent C-N elimination in situ. A one-pot procedure for this addition-elimination was also developed. The reaction could tolerate a broad substrate scope and give the corresponding alkenylazaarenes in high yields.
