Radical Process

A nitrogen-centered radical-mediated strategy is described to synthesize functionalized 3-acylcoumarins. This process is enabled by visible-light-induced acylation/cyclization reactions of alkynoates with various acyl oxime compounds in acetonitrile. The difunctionalization of...

New Strategy

Phosphonium ylides have shown their synthetic usefulness in important carbon–carbon bond formation processes. Our new strategy employs phosphonium ylides as novel carbyne equivalents and features a new approach for constructing carbon–carbon bonds from alkenes.

Intermolecular Reactions

Correlation between yield and reduced mass of raw materials in intramolecular C-N, C-C, C-O coupling reactions and intramolecular/intermolecular Diels-Alder reactions was revealed. The regression equation was found to be the same as that of intermolecular reactions; yield = -0.1861<i>M</i><sub>AB</sub>/(<i>n</i><sub>A</sub><i>n</i><sub>B</sub><i>n</i><sub>I</sub>)+100.0, where <i>M</i><sub>AB</sub> is the reduced mass per mole and <i>n</i><sub>A</sub> and <i>n</i><sub>B</sub> are the total number of each reaction site in molecular A and molecular B in the reaction system, and <i>n</i><sub>I</sub> is the number to distinguish whether it is a intramolecular reaction or intermolecular reaction.
