Synthesis of Diverse β,β‐Diaryl β‐Siloxy Diamines and Application as Organocatalysts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
β,β‐Diaryl‐β‐siloxy diamines are developed as diverse diamine organocatalysts. The synthetic methodology enables structural diversification through Grignard reactions, as well as subsequent silylation and amination. These diamines catalyzed enantioselective fluorination of β‐diketones in water with improved enantioselectivity (up to 53% ee) compared to

Intramolecular Heck Reactions of Cyclic Sulfonamides: Regiochemical Trends and Reductive Cleavage

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The synthesis of a new class of cyclic sulfonamides and their subsequent conversion into substituted N‐heterocycles is reported. Methyl‐substituted tetrahydropyridine and tetrahydro‐azepine Heck precursors are prepared and cyclized to provide a variety of regioisomeric products.
