BackgroundPatients with lung cancer are among the most frequent visitors to emergency departments due to cancer-related problems, and the prognosis for those who seek emergency care is dismal. Given that patients with lung cancer frequently visit hea

Cycloaddition reactions provide an expeditious route to construct ring systems in a highly convergent and stereoselective manner. For a typical cycloaddition reaction to occur, however, the installation of multiple reactive functional groups (π-bond

Pd(II)–catalyzed C(sp(3))–H olefination of weakly-coordinating native amides is reported. Three major drawbacks of previous C(sp(3))–H olefination protocols – 1) in situ cyclization of products, 2) incompatibility with α-H-containing substra

We report the development of Pd(II)-catalyzed C(sp(3))–H arylation of Weinreb amides. This work demonstrates the first example of using Weinreb amide as a directing group for transition metal-catalyzed C(sp(3))–H activation. Both the inductive ef

Palladium-catalyzed methylene β-C(sp3)–H arylation of aliphatic ketones using a transient directing group is developed. The use of α-benzyl β-alanine directing group that forms a six-membered chelation with palladium is crucial for promoting the

Pd-catalyzed C–H functionalizations promoted by transient directing groups remain largely limited to C–H arylation only. Herein, we report a diverse set of ortho-C(sp2)–H functionalizations of benzaldehyde substrates using the transient directi

Pd(II)–catalyzed C(sp3)–H olefination of native amide substrates was developed. To utilize the extremely weak-coordinating carbonyl-coordination of amides, an electron-deficient pyridinesulfonic acid ligand was designed. Structurally diverse amid
