Modular Synthesis of Benzocyclobutenes via Pd(II)-Catalyzed Oxidative [2+2] Annulation of Arylboronic Acids with Alkenes

Qian Wang, Jieping Zhu, Anne-Clémence Corminboeuf, Takuji Fujii, Simone Gallarati

Benzocyclobutenes (BCBs) are highly valuable compounds in organic synthesis, medicinal chemistry, and materials science. However, catalytic modular synthesis of functionalized BCBs from easily accessible starting materials remains limited. We report herein ...

Engineering of chitosan-based derivatives for non-viral gene delivery

Laura Camille Louise Nicolle

Gene therapy offers the possibility to treat or even cure diseases originating from genetic defects by introducing a therapeutic gene in target cells or correcting the initial defective gene. Amongst different options, non-viral vectors rely on the deliver ...

Natural Product Synthesis Enabled by Domino Processes Incorporating a 1,2-Rearrangement Step

Qian Wang, Jieping Zhu, Bastien Delayre

The art of natural product total synthesis is closely associated with two major determinants: the development/application of novel chemical reactions and the innovation in strategic use of classic organic reactions. While purposely seeking/applying a new s ...

New Vinylation and Alkynylation Strategies with Hypervalent Iodine Reagents and Diazo Compounds

Guillaume Dominique Pisella

The development of a sequential copper-catalyzed oxy-alkynylation/intramolecular [4+2] cycloaddition of allenes and arenes was investigated at first. This one-pot protocol allowed the construction of complex polycylic architectures with high efficiency fro ...

Synthetic methodologies for C-C and C-N bond formation involving alkyl radicals

Guido Barzanò

C-C and C-N bonds are some of the most common structures in molecules ranging from drugs to catalysts and to food additives. Many coupling reactions were developed to form these types of bonds with excellent selectivity and good performance. Still, the syn ...
