Consecutive Four-Component Coupling-Addition Aza-Anellation Pictet–Spengler Synthesis of Tetrahydro-β-Carbolines: An Optimized Michael Addition and Computational Study on the Aza-Anellation Step

Kai Ries, Françoise A. Aouane & Thomas J. J. Müller · Organics · 2023

Starting from acid chlorides, alkynes, tryptamines, and acryloyl chloride, 21 densely substituted tetrahydro-β-carbolines were prepared in a four-component, one-pot reaction. In this study, the aza-Michael addition step to generate intermediate enaminones was optimized in the pre...

An Unexpected Reaction between Diaryliodonium Salts and DMSO

Konrad Kepski & Wesley James Moran · Organics · 2022

Diaryliodonium salts are useful arylating reagents that have been exploited widely. In this Communication, we demonstrate that heating diphenyliodonium triflate in the solvent DMSO leads to an unexpected arylation reaction. It is postulated that arylation of DMSO at oxygen, follo...
