The synthesis of atalantrenes B, C and D, styrene-dimers from the seeds of Atalantia monophylla
Nielsen, Alexander J.,Deng, Zirou,McNulty, James
, (2021)
Concise syntheses of three recently reported natural products from Atalantia monophylla are reported. The syntheses required the preparation and careful dimerization of highly electron rich styrenes under acidic conditions. The present work adds to a growing body of evidence that demonstrates that synthetic utility of chiral phosphoric acids in asymmetric reactions using styrene-type compounds.

In the past few years, Ru and Ir catalyzed photoredox radical coupling reactions have been widely applied in organic synthesis. In contrast, the applications of Cu catalysts in photoredox organic transformations were limited. We here report the first example of photoinduced, Cu-catalyzed three component cyanofluoroalkylation of alkenes by directly using fluoroalkyl iodides as fluoroalkylation reagents.

The reactivity of sterically hindered N-tosylhydrazones 2 featuring ortho/ortho′-substituents on the aromatic ring with various ortho-, meta-, and para-substituted aryl halides 3 was investigated. To accomplish successfully this challenging coupling, fine-tuning of the reaction conditions were required. The newly established PdCl2(MeCN)2/Xphos/ NaO-t-Bu/F-benzene system in a sealed tube is compatible with a broad spectrum of both coupling partners, regardless of their electronic and steric nature. This protocol has been applied successfully to the synthesis of a xanthene derivative.
