Deconstructive Radical-Radical Coupling for Programmable Remote Acylation. [PDF]
A unified approach to access a variety of 1,n‐dicarbonyls through a radical‐promoted deconstructive process utilizing dual photocatalysis/carbene catalysis is reported. The utility of this strategy is demonstrated with a broad scope with robust functional group tolerance along with application in the preparation of γ‐amino esters, three‐component ...

Novel Sulfur-Containing Polyurethanes using 5-(Chloromethyl)Furfural as a Renewable Building Block. [PDF]
A novel methodology is presented for synthesizing biomass‐derived diols using 5‐(chloromethyl)furfural, thiols, and mild reaction conditions. These innovative diols are subsequently utilized in the production of new polyurethanes via polyaddition with both commercially available and biomass‐derived diisocyanates.

Total Synthesis of Isodaphlongamine H by Iridium-Catalyzed Reductive [3 + 2] Cycloaddition of N-Hydroxylactam. [PDF]
The total synthesis of isodaphlongamine H was accomplished by a lactam strategy. This strategy started with alkylation and N‐oxidation of a readily available chiral lactam. For the key functionalization of the amide carbonyl, an iridium‐catalyzed reductive [3 + 2] cycloaddition of the N‐hydroxylactam afforded the tricyclic isoxazolidine, which was ...

Strategy-Level Prodrug Synthesis. [PDF]
Prodrug approaches can be expanded by increasing options for controlling site‐selective functionalization, boosting the range of linking groups, and enhancing the chemoselectivity of reactive group incorporation. This Concept describes strategy‐level prodrug synthesis, whereby these issues are addressed at an early stage of a sequence.

SmI<sub>2</sub>-Catalyzed Coupling of Alkyl Housane Ketones and Alkenes in an Approach to Norbornanes. [PDF]
Samarium diiodide (Sml2) is an effective catalyst for the mild, atom‐economical coupling of bicyclo[2.1.0]pentane, or housane, ketones, and electron‐deficient alkenes to give functionalized norbornane structural motifs not easily accessible by classical cycloaddition approaches.
