Most of the available information on studying under the challenging conditions brought about by the COVID-19 pandemic emphasizes a variety of aspects on how to digitalize the whole teaching process. Thus, several useful and potentially game-changing

The rapid assembly of complex scaffolds in a single step from simple precursors identifies as an ideal reaction in terms of efficiency and sustainability. Indeed, the direct single-step synthesis of complex alkaloid frameworks remains an unresolved p

Thiocyanates, versatile building blocks in organic synthesis, are shown to be easily accessible via an interrupted Pummerer reaction of sulfoxides. This facile dealkylative functionalization proceeds under mild conditions through electrophilic activa

A method for the Brønsted acid promoted desulfination of aryl sulfoxides is presented. In the presence of a thiol, electron-rich sulfoxides undergo C–S bond cleavage to give the corresponding protodesulfinated arenes and disulfides.

Although sulfur ylides are textbook reagents in organic synthesis, surprisingly little variation of substituents on sulfur is usually observed. In particular, vinylsulfonium ylides have been neglected so far. Herein, we present a study on their synth

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

During comparative analysis on Palicourea species from Costa Rica, two unusual loganin derived tryptamine–iridoid alkaloids were isolated from an accession of Palicourea crocea . Besides the already known brachycerine ( 2 ), palicroceaine ( 1 ) fea

Four varieties of carbonyl sandwich Compounds with adjacent carbons sandwiched between two carbonyl (C=O) centers turn up frequently in organic chemistry. When these central carbons each have a substituent, there are four possible mutual geometries,
