An efficient metal-free oxyarylation of electron-poor alkynes with pyridine N-oxides has been developed. This transformation affords meta-substituted pyridines analogous to the drug metyrapone in high regioselectivities. Density functional theory (DF

A mechanistic investigation of the acid-catalysed redox-neutral oxoarylation reaction of ynamides using electrospray ionisation mass-spectrometry (ESI-MS) and quantum chemical calculations (DFT and MP2) is presented. This study reveals the diversity

A unified route to oxygenated Plakortin pentalenes is described. Along with the previously disclosed total synthesis of hippolachnin A, the potential of this scheme is demonstrated by the first total synthesis of gracilioether E, as well as the total

The first total synthesis of the marine polyketide (±)-hippolachnin A has been achieved in nine linear steps and an overall yield of 9 %. Rapid access to the oxacyclobutapentalene core structure was secured by strategic application of an ene cycliza

The synthesis of α-amino carbonyl/carboxyl compounds is a contemporary challenge in organic synthesis. Herein, we present a stereoselective α-amination of amides employing simple azides that proceeds under mild conditions with release of nitrogen g

Breaking good: The amide bond is widely recognized as the strongest bond among the carboxylic acid derivatives. Therefore, the potential of amides to serve as synthetic building blocks has remained mostly untapped thus far. This Highlight describes a
