novel approach to generate β-acetylamino acrylosulfones using the photocatalyst UiO-67-Ru under visiblelight has been developed. The entire reaction is applicable to sulfone-containing skeleton and exhibits good substrate scope. UiO-67-Ru-catalyzed protocol provides a sustainable and efficient access to construct a variety of sulfonesvia the direct functionalization of C–H bonds.

Inverse Electron-Demand Aza-Diels–Alder Reaction of Cyclic Enamides with 1,2-Diaza-1,3-dienes in Situ Generated from α-Halogeno Hydrazones: Access to Fused Polycyclic Tetrahydropyridazine Derivatives
efficient inverse electron-demand aza-Diels–Alder reaction of cyclic enamides and 1,2-diaza-1,3-dienes, which could be readily formed in situ from α-halogeno hydrazones and a base, has been successfully developed. With the developed approach, a wide range of fusedpolycyclic tetrahydropyridazines were smoothly obtained in up to 99% yield under benign reaction conditions. This reaction concept was also extended

the synthesis of C–P bonds has been an important focus of research. We herein report a Pd‐catalyzed enamidoC(sp2)–Hphosphorylation for direct construction of C–P bonds under simple and convenient conditions without the need for additional ligands or directing groups. The present reaction can tolerate a wide range of functional groups, and furnish a variety of phosphorylation products including t
Brønsted Acid Catalyzed Addition of Enamides to <i>ortho</i>
-Quinone Methide Imines-An Efficient and Highly Enantioselective Synthesis of Chiral Tetrahydroacridines
The direct and highly enantioselective synthesis of tetrahydroacridines was achieved through the phosphoric acid catalyzed addition of enamides to in situ generated ortho‐quinone methide imines and subsequent elimination. This novel one‐step process constitutes a very efficient, elegant, and selective syntheticapproach to valuable N‐heterocycles with a 1,4‐dihydroquinoline motif. By subsequent highly
