products, and biologically active compounds showcase the robustness and functional‐group tolerance of the reaction. The key to the success of the reaction could be the possible formation of the strong Si−O bond via a Brook‐type rearrangement. Given its simplicity and efficiency, this ligation has the potential to unfold new applications in the areas of medicinal chemistry and chemical biology.

Efficient and enantioselective: Using the iodine‐bridged dimeric iridium complex [Ir(H)[(S,S)‐(f)‐binaphane]}2(μ‐I)3]+I− (1) a wide range of tetrahydroisoquinoline alkaloids, including the substructure of the pharmaceutical drug solifenacin, were obtained with excellent enantioselectivities and high turnover numbers (see scheme).
Iodine catalyzed synthesis of 2,5-substituted oxazoles from N-arylethylamides through intramolecular C(sp3)–H functionalization under metal-free conditions is described.

Described herein is a simple, novel, one-pot acylamination reaction of unactivated alcohols. This reaction employs the combination of PCl3 and triflic anhydride (Tf2O) or copper triflate Cu(OTf)2, which serves as a source of P(IV)-activated complex for nitriles to react under the Ritter-type mechanism. The synthetic utility of Tf2O-promoted reactions was demonstrated by its effectiveness to generate different

Selectivity in organic chemistry is generally presumed to arisefrom energy differences between competing selectivity-determining transition states. However, in cases where static density functional theory (DFT) fails to reproduce experimental product distributions, dynamic effects can be examined to understand the behavior of more complexreaction systems. Previously, we reported a method for nitrogen
