Commercially available tris(3,6-dioxaheptyl)amine (TDA-1) is an effective phase transfer catalyst for reactions with sodium-potassium alloy in tetrahydrofuran. Deoxygenation of acetates, dehalogenation, and hydrolysis of tosylates and mesylates proceed in high yield. The use of a deuterated alcohol during deoxygenation reactions leads to site-specific deuteration.
A highly efficient manganese-catalyzed redox-neutral thiolation of alkylhalides with thioformates was developed. This method could be extended to the late-stage thiolation of structurally complex natural products and pharmaceuticals by using easily synthesized thioformates as thiyl radical precursors.
